The ultra wide band (UWB) antennas play a vital role in supporting different wireless standards and are suitable for wide variety of applications. This paper is aimed to present a novel UWB dual notch microstrip antenna with modified ground plane. The antenna is designed to operate in UWB ranging from 2 GHz to 12 GHz with multi band operation. This will help in operating the antenna for different operations independently. The proposed structure will operate in two notch bands 3.3-4 GHz (Wi-MAX), 5.05-5.9 GHz (WLAN) and the structure is suitable for long distance communications because of its increased directivity. The structure can also be used for X-Band applications for various applications of traffic control, weather forecasting and vehicle speed detection systems. It is observed that, the proposed structure is offering a gain of 5.2 dBi with improved directivity with a beam width of 42.230. This makes the antenna structure suitable for long distance satellite communications. The antenna is supporting the circular polarization at higher the frequencies and can be useful for the upcoming 5G mobile applications. Moreover, the proposed structure offers the less interference at the receiver. The structure is found to be smaller in dimensions, easily fabricated at low costs and can be integrated into any compact wireless devices. The structure is simulated using a commercially available software Ansys-HFSS and is analyzed.

Distributed Antenna Systems and Compact Base Stations: When to Use Which?Frank Rayal
Distributed Antenna Systems grew from the need to provide wireless coverage and capacity to areas of highly concentrated users. More recently, as capacity and coverage demands expanded and some municipalities passed strict edicts against constructing towers, DAS systems got deployed along streets to provide service in the urban and suburban outdoors. Another solution to add capacity and coverage uses compact base stations which are getting large attention from both a cost and performance perspective. From a deployment perspective, they provide similar network architecture to DAS, which raises the question on how these two solutions compare. This application note will highlight the areas where each solution makes economic and technical sense.

Developing an actual very high frequency antenna using genetic algorithmseSAT Journals
Abstract Antenna for the 88-108MHz Very high frequency (VHF) broadcast audio frequency-modulation (FM) band. The antenna is intended tofit in the flat area inside the head-band of an over ear hearing-protector headset. The space for the antenna is limited by an existing head-band design, where the unused internal area is the space studied in this thesis. A genetic algorithm is described for the multiple objective optimization of the antenna matching and radiation pattern optimization. The results of multiple genetic algorithm evaluations are described, and possible further improvements outlined. Progress is made on the development of the antenna. The antenna radiation pattern is evolved in desirable way, but a difficulty in solving the antenna matching problem is identified. Research for resolving the antenna matching problem is described in this paper Keywords: Antenna, Modulation, Genetic Algorithm, Frequency, Head-Band, Very High Frequency Broadcast.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

"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.
PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert

3. Passive Material
Introduction with Passive Material
Coaxial cable received its name because it includes one physical channel that carries the signal surrounded -- after a layer of insulation -- by another concentric physical channel,
both running along the same axis. The outer channel serves as a ground. Many of these cables or pairs of coaxial tubes can be placed in a single outer sheathing and, with
repeaters, can carry information for a great distance.
Jumper cables is a smaller and more bendable corrected cable which is used to connect antennas and other components to network cabling. Jumpers are also used in base stations
to connect antennas to radio units. Usually the most bendable jumper cable diameter is lower than 1/2".
A leaky feeder is a coaxial cable that has small sections of its copper shielding stripped away to allow radio frequency (RF) signals to escape. Leaky feeders, which act as extended
antennas, are also called radiating cables. Leaky feeders are used in places where the actual structure makes RF communication difficult.

Introduction with Passive Material
Cable Connector Cable Tray Antenna Support
A coaxial RF connector (radio frequency connector) is an electrical connector designed to work at radio frequencies in the multi-megahertz range. RF connectors are
typically used with coaxial cables and are designed to maintain the shielding that the coaxial design offers.
The SPB-RF Cable Tray System has a return flange on the sides and is designed with no sharp edges. The cable tray system features slot patterns allowing for optimal and
efficient positioning of equipment and easy access for cable ties and other fixings.
In radio engineering, an antenna is the interface between radio waves propagating through ...Antenna may refer broadly to an entire assembly including support structure,
enclosure (if any), etc. in .... An antenna counterpoise, or ground plane, is a structure of conductive material which improves or substitutes for the ground.
5. Passive Material
Introduction with Passive Material
The RF tap is basically a small antenna that is inserted into the main coaxial line, which couples a small portion of the tapped branch into the new branch. A typical
application for an RF tap would be to branch several antennas off of a local branch.
The directional coupler can be used in situations where a small amount of power needs to be drawn off a main branch. Directional couplers also come in a multitude of
values. With a coupler, most of the signal is transmitted to the “through” port while a small portion of the signal is transmitted to the “coupled” port. The method used to
couple the signal is different.
Splitter is a resistive network divider which use to break one input power into two or more outputs of equal power. There are two components to the splitter loss. The
first is the loss associated with actually splitting the signal into multiple outputs, and the second is the insertion loss due to ohmic (resistive) loss.
