In this paper, a novel directional super wide band micro strip antenna based on a simple and new geometry has been proposed. The antenna exhibits the widest bandwidth ever reported to the authors’ knowledge from 50 GHz to 200 GHz. Its radiation pattern is approximately steady in the frequency ranges of 50 GHz to 200 GHz. The antenna consists of a club-like radiating patch, a combination of three circular patches, and a partial ground structure. Moreover, the proposed antenna has a compact volume of 24 mm × 18 mm × 0.787 mm on a RT Duroid substrate with a relative dielectric constant of 2.2. RT Duroid has very low loss characteristic and therefore the loss of the antenna will be very little. The simulation is performed by CST Microwave Studio simulator. Antenna design and the simulation results of radiation pattern and gain are presented and discussed in detail. Results show that the performance is very excellent in full band.
