摘要：

A unique geometry of a square patch antenna with an embedded asymmetrical pi-shaped slot for circular polarization is presented. The proposed structure has an aperture coupled feed which is matched over a very wide frequency band. This is accomplished by incorporating an oval shaped stub at the end of the single microstrip feed. The antenna shows a 3-dB axial ratio bandwidth of 3.9 % (2.50-2.60 GHz) with respect to the measured minimum axial ratio frequency of 2.56 GHz. The 10-dB return loss bandwidth measured is 40.23 % (2.32-3.35 GHz) with respect to 2.56 GHz. The antenna gain is > 8.2 dBi in the circularly polarized band. The antenna is well suited for use in circularly polarized antennas and arrays for wireless communication.
