摘要

This paper proposes a novel method of building electronically beam steerable antenna system using active frequency selective surfaces (AFSS). The design methods and special principals of the active frequency selective surfaces built for this kind of antenna are studied. The antenna system is fabricated and experimentally investigated. The front-to-back ratio is more than 30 dB with the a null point of ${-}$ 59 dB. The gain can be promoted to be 7.0 dBi. Furthermore, multi-beam functionality is achieved and the amplitudes of the beams can be controlled.
