摘要: This paper presents a semiconductor reflector antenna for use in reconfigurable telecommunication systems. The quasi-metallic characteristic was obtained by formation of high conductivity plasma regions placed at PIN diodes, thereby controlling the beam direction and gain antenna. constant current regulator necessarily designed to obtain expected carrier density maintain stable operation diodes. measured reflection coefficient peak around center frequency 5.5 GHz were −13.5 dB 5.4 dBi, respectively.
