Wideband Star-Shaped Microstrip Patch Antenna

By M. Abbaspour and Hamid Reza Hassani
Progress In Electromagnetics Research Letters, Vol. 1, 61-68, 2008


A new wideband and small size star shaped patch antenna fed capacitively by a small diamond shape patch is proposed. To enhance the impedance bandwidth, posts are incorporated under the patch antenna.HFSS high frequency simulator is employed to analyze the proposed antenna and simulated results on the return loss, the E and H-plane radiation patterns and Gain of the proposed antenna are presented at various frequencies.The antenna is able to achieve in the range of 4-8.8 GHz an impedance bandwidth of 81% for return loss of less than -10 dB.
