Abstract

In the paper, patch antenna is designed in Ansoft HFSS V13. It is used for S-band applications such as WiMAX. Design of a patch antenna is mainly circular, E-shaped etc. Particularly circular patch antenna are used as they provide large Gain with higher Bandwidth. The E-shaped patch antenna is designed for minimum Return Loss. Hence a new system is proposed where in combination circular and E-shaped is carried out with higher Gain, less Return Loss and maximum Bandwidth. The operating frequency of this antenna is 3.51 GHz. The minimum Return Loss at 3.51 GHz is −19.6 dB and Gain is 9.13 dB with 1.2 VSWR.
