| Sumario: | A parasitic surface (PS) based wide beam width patch antenna operating at 5 GHz is presented. The half-power beam widths (HPBWs) of the patch antenna are improved by the PS, which is composed of a parasitic ring and six parasitic patches. The parasitic ring is used to increase the HPBW in the E-plane, while the six parasitic patches are used to increase the HPBW in the H-plane. Simulation results show that the PS has little effect on the impedance bandwidth of the patch antenna but can increase the HPBW by 66.7° (from 85.1° to 151.8°) in the E-plane and 88.7° (from 78.9° to 167.6°) in the H-plane at 5 GHz. At the same time, the PS decreases the boresight gain of the patch antenna from 5.42 to 3.06 dBi. Measurement results agree well with the simulation. |
