Abstract

A technique is investigated for achieving broadband properties by controlling the operation frequency of microstrip antennas. The control is achieved by applying DC and AC bias to the microstrip antenna. Air gap antenna with pzt post and microstrip antenna with simple rectangular patch on the $LiNbO_3$ substrate were fabricated. In the case of Air gap antenna, the variation of operating frequency was 11Mhz and $LiNbO_3$ antennas was 11Mhz. Also, frequency scanning was achieved by appling AC bias.
