Ultra wide band crescent antenna with enhanced maximum gain

Abstract

In this study, an ultra wide band microstrip antenna fed by coplanar wavequide with enhanced maximum gain is designed. Size of the designed antenna is 60×38mm and the dielectric material (Rogers RO3006) with relative dielectric constant er=6,15 is used. At the designing stages, the effects of the modifications on the gain is examined too. The gain of the modified antenna is increased with minimum 1dB and maximum 3 dB at whole bandwith.
