Abstract
This paper describes a novel technique for increasing the operational frequency bandwidth of microstrip patch antennas, by using varactor diodes at the radiating edges of the structure. Theoretical and experimental results confirm that bandwidths of the order of 30% are achievable compared to 1-2% for the unloaded patch radiator.
