A Compact Directional Super-wideband Antenna

In this paper, we propose a novel directional super-wideband microstrip antenna based on a simple and new geometry which covers the frequency range of 11 GHz to200 GHz. Its radiation pattern is approximately steady in the frequency range of 50 GHz to 200 GHz. The antenna consistsof a club-like radiating patch, a combination of threecircular patches, and a partial ground structure. Moreover, the proposed antenna has a compact volume of 24 mm × 18mm × 0.787 mm on a RT Duroid substrate with a relative dielectric constant of 2.2. Antenna design and the simulationresults of radiation pattern, and gain are presented and discussed in detail
