Design & Simulation of E-Shaped Micro Strip Patch Antenna for GPS ApplicationIJERA Editor
Micro strip antennas are widely used in many applications due to their low Profile, low cost and ease of fabrication. In some applications it is desired to have a dual band or multiband characteristics. This paper presents the design and simulation of E-shape micro strip patch antenna with wideband operating frequency for wireless application. The shape will provide the broad bandwidth which is required in various application like remote sensing, biomedical application, mobile radio, satellite communication etc. The antenna design is an improvement from previous research and it is simulated using HFSS (High Frequency Structure Simulator) version 13.0 software. GPS provides specially coded satellite signals that can be processed with a GPS receiver enabling the receiver to compute position, velocity and time. Coaxial feed or probe feed technique is used. Parametric study was included to determine affect of design towards the antenna performance. Radiation performance of the designed antenna is simulated using the HFSS software version 13.0. The performance of the designed antenna was analyzed in term of bandwidth, gain, return loss, VSWR, and radiation pattern. The design was optimized to meet the best possible result. Substrate used was air which has a dielectric constant of 1.0006. The results show the wideband antenna is able to operate from 8.80 GHz to 13.49 GHz frequency band with optimum frequency at 8.73 GHz. Due to the compact area occupied. The pro-posed antenna is promising to be embedded within the different portable devices employing GPS applications.

MINIATURISATION OF PATCH ANTENNA USING NOVEL FRACTAL GEOMETRYIAEME Publication
In the Field of low profile antennamicro strip patch antennas have attracted many researchers due to small sizeand low cost of fabrication. One of trending member of new designs is Fractalantenna. Fractal shapes are recursive/repetitive self-similar geometries, dueto this self-similarity they can provide high gain, multiband, widebandsolutions and design miniature antenna. Fractal shapes are widely used incomputing, analysis and design; recent trends suggest positive outcomes ofusing fractal shapes in electromagnetics and communication system. In thispaper Jerusalem cube fractal shape is introduced in probe fed conventionalpatch antenna for L1 band. A dual band antenna resonating at 1.41 GHz (L) and3.37 (S) GHz, band is constructed using said fractal shape.
In the recent years the improvement in communication systems requires the development of low cost, minimal weight, low profile antennas that are capable of maintaining high performance over a wide spectrum of frequency. This technological trend has focused much effort into the design of a Micro strip patch antenna. In this paper, we designed a rectangular micro strip patch antenna at 3.8GHz and study the effect of antenna dimension Length (L), Width (W), substrate parameter relative dielectric constant (€r ) substrate thickness (h) and radiation pattern using Ansoft HFSS. It even describes the increasing effect of Gain and Directivity. The Proposed antenna also presents the detail steps of designing the micro strip antenna and the simulated result. The feeding technique used to feed the antenna is coaxial probe feeding technique. Micro strip patch antenna is used in many fields like Antenna and mobile communication, Filters, PCB board model and EMC and EMI. Rogers RT/duroid 5880 (tm) substrate with a dielectric constant of approximately 2.2, is a feed and has a partial ground plane. The gain and directivity of the designed antenna is 7.7082 dB and 7.76882dB respectively.
A small H-shaped microstrip patch antenna (MPA) with enhanced bandwidth is presented. The H-shaped antenna is first studied and then fully simulated by HFSS. A dual U slot H patch configuration is proposed to increase the narrow bandwidth, radiation efficiency and directivity. A novel H-shaped patch antenna suitable for wireless and satellite communications is presented. This paper presents the dual U slot H-shaped microstrip patch antenna feed by transmission line. The decrease in the prices of handheld devices and services has made available on the move internet and web services facility to the customers, small antennas requirement are increasing. In this paper H-shaped patch antenna is designed using FR4 substrate. The proposed modified H shaped antenna is designed and simulated using HFSS and caters to various wireless applications such as WiMAX, Wi-Fi, UMTS and Digital Multimedia Broadcasting (DMB) e.g. T V, etc.

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.
Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Abstract
In this paper a novel design of small sized, rectangular patch antenna with coaxial fed low profile antenna with
step type slots at the four sides, circular slot at the center is proposed for the frequency of C Band application
with the substrate RT duroid 5880(™) whose relative permeability
and a loss tangent are 2.2,
0.0009respectively.Withthe above specifications Designed antenna parameters like return loss which is 38.4225dB at 3.7374GHz with elliptical polarization, along θ, Ø directions, radiation pattern in 2D & 3D where
the 2-D gain is 7.598dB, along with gain and radiation pattern E&H field and current distributions are simulated
using HFSS 11.0. The measured parameters satisfy required limits hence making the proposed antenna suitable
for s-band weather radar applications.

Introduction
The S band is part of the microwaveband of
the electromagnetic spectrum. With frequencies that
range from 2 to 4 GHz. The S band is used for radar
applications like weather, surface ship radarand also
for satellite communication.Theradar with 10cm are
short-band range are roughly from 1.55 to 5.2 GHz.
The 2.6 GHz range is used for China Multimedia
Mobile
Broadcastinga
radio(satellite)
andm
TV(mobile). In some countries, S band is used for
Direct-to-Home satellite television. The frequency
typically allocated for this service is 2.5 to 2.7 GHz
(LOF 1.570 GHz). Amateur radio and amateur satellite
operators
have
two
S-band
allocations,13cm(2.4 GHz)and9
cm
(3.4 GHz).Radar applications use relatively high
power pulse transmitters and sensitive receivers. So
radar is operated in bands not used for other purposes.
Most radar bands are part of the microwavespectrum,
although certain important
applications
for
meteorology make use of powerful transmitters in the
UHF band.
Micro strip patch antennas are widely used
because of its lightweight, compact size, they are easy
to integrate and finally cost effective.
However, Major Diminishing factor of patch
antennas is their narrow bandwidth due to surface
wave losses andfor better performance size of patch
must be large. As a result various techniques to
enhance the bandwidth are proposed. Techniques to
reduce size include different structural techniques,
shorting pin or plate techniques, where a micro strip
line or patch is shorted with the ground plane of the
antenna. Different loading techniques can be used;
such as using external lumped components to reduce
www.ijera.com
the size of the antenna, which result in reduced overall
performance and gain, while increasing the cost of the
antenna.
Keeping in view of inserting slots in patch
antenna for greater band of operationwithout
increasing its size.Coaxial fed Rectangular patch
antenna with step slots at the foursides, center with
circular slot wasproposed keeping in view of weather
radar applications.
The proposed antenna parameters like return
loss with elliptical polarization, gain along θ, Ø
directions, radiation pattern in 2D & 3D, E & H field
and current distributions are simulated using HFSS
11.0 which is a high-performance full-wave
electromagnetic(EM) field simulator for arbitrary 3D
volumetric passive device modeling that takes
advantage of the familiar Microsoft Windows
graphical user interface. Ansoft HFSS can be used to
calculate parameters such as S-Parameters, Resonant
Frequency, and Fields.

Antenna Design considerations
The proposed structure of the antenna is
shown in Figure. (1). The antenna is simulated using
RT duroid substrate with a dielectric constant and loss
tangent are 2.2, 0.0009. The thickness of the substrate
is 0.32cm. The size of the antenna is 0.2mm, which is
suitable for most Radar applications. Patch with step
slots on four sides, center with circularslot is proposed
for the frequency of S Band application.

The patch can also be fed with a probe
through ground plane. The probe position can be inset
for matching the patch impedance with the input
impedance. This insetting minimizes probe radiation.
The ease of insetting and low radiations is advantages
of probe feeding as compared to micro strip line
feeding. The dimensions of shaped patch shown in

E-field pattern
An electric field can be visualized by drawing
field lines, which indicate both magnitude and
direction of the field. Field lines start on positive
charge and end on negative charge. The direction of
the field line at a point is the direction of the field at
that point. The relative magnitude of the electric field
is proportional to the density of the field lines.

H-field Pattern
In the case of the same linearly polarized
antenna, this is the plane containing the magnetic field
vector and the direction of maximum radiation. The
magnetic field or "H" plane lies at a right angle to the
"E" plane. For a vertically-polarized antenna, the Hplane usually coincides with the horizontal/azimuth
plane. For a horizontally-polarized antenna, the Hplane usually coincides with the vertical/elevation
plane.

The triangles show the current distribution.
Here the number of triangles inside the patch is more
than those on the substrate i.e.the current distribution
in the patch are more when compared to that inside the
substrate as in Fig10.
Fig7 H-Field pattern.
Vector E- Field
The field equations of Einstein Cartan Evans
(ECE) are used to develop the concept of the static
electric field as a vector boson with spin indices −1, 0,
+1, which occur in addition to the vector character of
the electric field. The existence of the electric vector
boson in physics is inferred directly from Cartan
geometry, using the concept of a spinning space-time
that defines the electromagnetic field. When the
electromagnetic field is independent of the
gravitational field the spin connection is dual to the
tetrad, producing a set of equations with which to
define the electric vector boson. Angular momentum
theory is used to develop the basic concept.
Radiation pattern
The radiation
pattern or antenna pattern
describes the relative strength of the radiated field in
various directions from the antenna, at a constant
distance.
