Modelling of Path Arrival Rate for In-Room Radio Channels with Directive Antennas [PDF]

, 2017
We analyze the path arrival rate for an inroom radio channel with directive antennas. The impulse response of this channel exhibits a transition from early separate components followed by a diffuse reverberation tail.

A wideband and high‐gain switched‐beam antenna system using active frequency selective surface

IET Microwaves, Antennas & Propagation, 2023
Antennas using the active frequency selective surface (AFSS) can achieve fast beam‐scanning ability at a low cost. In this study, a switched beam antenna with a high gain and 360° coverage in the horizontal plane is proposed.
