A Fabry Perot cavity (FPC) antenna consists of a primary radiator at the base of a dielectric cavity sealed with a partially reflecting surface at the other end. Excitation from the radiator is partially reflected by the ...

We analyze the performance of a radar in an environment where clutter is constituted by discrete scatterers whose radar cross-sections are comparable to that of the target. An indoor radar deployment to detect humans in ...

There has been a growing interest in building through-the-wall radars (TWR) for law enforcement, security and biomedical applications for tracking humans in urban environments. Designing the antennas for such systems is a ...

Rapid beam alignment is required to support high gain millimeter wave (mmW) communication links between a base station (BS) and mobile users (MU). The standard IEEE 802.11ad protocol enables beam alignment at the BS ...

Directivity of an antenna is a figure of merit which shows how effective an antenna is at transmitting / receiving in a desired direction. A highly directive antenna is useful for applications such as satellite communications ...

Radar systems for detecting the humans present behind the wall are powerful tools for law enforcement, military and elderly care. Walls are complex propagation mediums that introduce attenuation, refraction and multipath ...
