   Abstract:
   The possibility of building horizontally polarized, electronically steerable antenna by using active frequency selective surface is investigated. A 10-element electronically steerable antenna is realized by using an omni-directional Alford-loop antenna and active frequency selective surface columns with horizontal polarization sensitive direction. This antenna working at 2.4 GHz WiFi band is 360-degree steerable, and 1.7 dBi additional gain is achieved compared with the original Alford-loop antenna.
