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 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 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 presents a model for the control of the radiation pattern of a circular array of antennas, shaping it to address the radiation beam in the direction of the user, in order to reduce the transmitted power and to ...
