Abstract
Microstrip antennas suffer from having a very low bandwidth characteristic. This paper describes a novel technique for increasing the operational frequency range of microstrip patch antennas using varactor diodes at the radiating edges of the structure. Theoretical and experimental results confirm that bandwidths of the order of 30% are achievable with this method compared to the 1-2% bandwidth of the unloaded patch.
