Contrastive Parametric Analysis of Rectangular and Circular Microstrip Patch ...RSIS International
The comparative analysis of the rectangular and
circular patch antenna parameters is presented in this paper. To
make it acceptable for various wireless applications the selected
bandwidth is 10 GHz. HFSS is a software development tool
which is used for design and the study of the performance of the
presented antennas. The study gives the idea that the rectangular
patch antenna exhibits higher return loss than the return loss of
circular patch antenna whereas the rectangular patch antenna
has an improved VSWR value of 1.18 than that of the circular
patch with VSWR 1.27. Also the circular patch antenna offers
about 8% higher radio bandwidth and nearly 2.0dB less side
lobe power than that of the rectangular patch antenna. With rise
in the dielectric constant of the substrate material there is a
diminish structure of the patch antenna which leads to an
accommodation in bandwidth, impedance and efficiency of the
antenna. The simulated antennas are used in the field of 3G
communications due to the resonance frequency. The delineate
study about the dimensions such as width, length, feed point
location, ground dimension for each patch antenna of different
dielectric material are calculated and compared and the result
shows about the contrastive analysis of different patch antenna
performance parameter like VSWR, Reflection coefficient,
Bandwidth, Impedance, Mismatch loss, Directivity, Gain and

Abstract
Decision Tree learning algorithms have been able to capture knowledge successfully. Decision Trees are best considered when
instances are described by attribute-value pairs and when the target function has a discrete value. The main task of these
decision trees is to use inductive methods to the given values of attributes of an unknown object and determine an
appropriate classification by applying decision tree rules. Decision Trees are very effective forms to evaluate the performance
and represent the algorithms because of their robustness, simplicity, capability of handling numerical and categorical data,
ability to work with large datasets and comprehensibility to a name a few. There are various decision tree algorithms available
like ID3, CART, C4.5, VFDT, QUEST, CTREE, GUIDE, CHAID, CRUISE, etc. In this paper a comparative study on three of
these popular decision tree algorithms - (Iterative Dichotomizer 3), C4.5 which is an evolution of ID3 and VFDT (Very

Performance Analysis of Corporate Feed Rectangular Patch Element and Circular...Mohamed Hassouna
This paper present simple, slim, low cost and high gain circular patch and rectangular patch microstrip array antenna, with the details steps of design process, operate in X-band(8 GHz to 12 GHz) and it provides a mean to choose the effective one based on the performance analysis of both of these array antennas. The method of analysis, design and development of these array antennas are explained completely here and analyses are carried out for 4x2 arrays. The simulation has been performed by using commercially available antenna simulator, SONNET version V12.56, to compute the current distribution, return loss response and radiation pattern. The proposed antennas are designed by using Taconic TLY-5 dielectric substrate with permittivity, εr = 2.2 and height, h =1.588 mm. In all cases we get return losses in the range -4.96 dB to -25.21 dB at frequencies around 10 GHz. The gain of these antennas as simulated are found above 6 dB and side lobe label is maintained lower than main lobe. Operating frequency of these antennas is 10 GHz so these antennas are suitable for X-band application.

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.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.

transmitters for existing satellite communication
systems increases its availability and uses, specially
localized in places where mobile communications
infrastructures are not developed but satellite
communications has a full coverage.
The aim of this project is to design a system of
patch antenna (with flexible materials), operating at
406 MHz working as a distress beacon for
COSPAS-SARSAT search and rescue international
program.
We describe the design and performance of the
antenna.
The Cospas Sarsat – Search And Rescue
operation (SAR)- satellite system provides distress
alert and location data by using 406 MHz to assist
rescue operations at sea, in the air, or on land.
Figure1: COSPAS SARSAT overview
Between September 1982 and December 2017,
the COSPAS-SARSAT System provided
assistances in rescuing at least 46,553 people in
13,627 SAR events. In 2015, 2016 and 2017 (the
latest year for which statistics have been
compiled), COSPAS-SARSAT assistance
included the following [1]:
Years Events People Rescued
2017 963 2746
2016 876 2057
2015 718 2185

![The microstrip line consists dielectric
substrate and ground plane on the other
side of it. The microstrip patch antenna
has radiation on one side and ground on
the other. This is shown in Figure2.

- Low profile.
- Conformable to planar surfaces.
- Simple and cheap to manufacture.
- Easy to integrate with circuits.
- High radiation efficiency [2].

A patch antenna with flexible materials is
designed in this project. We measured
permittivity 𝜀 𝑟 = 3.72 , bandwidth is
0.52% ,Reflection coefficient is equal to -
13.63B and Resonance Frequency =
406MHz.
