Due to the many breakthroughs in the field of based pulse radars and ultra wide bandwidth (UWB) systems, researches of every component of those systems have been performed in recent years. As well as, in order to match the ...

This letter reports the concept and development of the first optically controlled reconfigurable antenna formillimeter-wave (mm-wave) applications. It is based on a slotted-waveguide antenna array and two photoconductive ...

This paper derives useful expressions for the synthesized beam statistics using poststatistic steenng (PSS), when three antennas are used in a spatial interferometer configuration for two­dimensional steering. These antennas ...

This paper uses artificial neural networks (ANN) to compute the resonance frequencies of rectangular microstrip antennas (MSA), used in mobile communications. Perceptron Multi-layers (PML) networks were used, with the ...

This paper presents a compact triple-band planar antenna. The prototype is based on a printed dipole which is excited with Split Ring Resonators (SRRs) as resonant elements to get three frequency bands. To validate the ...

This article presents the comparative analysis of antennas for Ground Penetration Radars (GPR) that operate in the VHF/UHF band around 200 MHz. Three types of antennas are optimized to improve bandwidth, obtain a gain ...

This paper presents the simulation, fabrication and complete characterization of a 2.4 GHz directional antenna designed for Wireless Sensor Network (WSN) nodes, named SPIDA. The use of this kind of antennas empowers the ...

The work investigates the electromagnetic performance of omnidirectional dual-reflector antennas designed to operate with a frequency bandwidth larger than 45% (25-40 GHz). We consider two antenna configurations, distinguished ...
