Wideband and small size star-shaped microstrip patch antenna

A new wideband and small size star-shaped patch antenna, fed by a small rectangular patch, is proposed. Simulation via a finite element program and measured results of return loss, and the E- and H-plane radiation patterns of the proposed antenna, are presented. The antenna is able to achieve in the range 5-9.3 GHz an impedance bandwidth of 63% for return loss of less than -10 dB.
