Reconfigurable Switched Beam Filtenna Based on Corner Cube Reflector and Combline SIW Resonator

This paper presents a reconfigurable band-pass filtering PIN Diode switch and a switched beam Filtenna. The combline substrate integrated cavity (SIC) resonators with distributed configuration are effectively employed to realize a three-state compact filtering switch. A corner cube reflector antenna has loaded the designed filtering switch to achieve a switched beam Filtenna with a fourth-degree Chebyshev response. The proposed switched beam Filtenna operates at 10 GHz with a bandwidth of 600 MHz, return loss of 15 dB, realized gain of 6.8 dBi, and covering beamwidth of 270 degrees.
