Abstract :
Most high-gain antennas are narrow band and most wideband antennas have low gains. In this paper we present a low-profile antenna with a large impedance bandwidth, and high gain over the large impedance bandwidth. This is achieved by integrating a wideband hybrid DR on patch (DRoP) with a surface-mounted short horn (SMSH). Performance of antennas with two types of DRoP configurations are studied. We experimentally achieved an excellent gain, greater than 9dBi, over a very wide 2:1 VSWR bandwidth of 28%.
