摘要

A wideband microstrip patch antenna is proposed in this communication for pattern diversity application. Broadside and omnidirectional radiation patterns are generated by the odd and even modes of a single circular patch. A compact feeding network based on coplanar waveguide is designed to provide in-phase and out-of-phase excitations, which can excite the two modes in wide bandwidth. The size of the feeding network is only 35 \times 14.5 mm². A prototype of the proposed antenna is fabricated and tested. The measured overlapped bandwidth (\vert \text{S}-{11}\vert < -10 dB and \vert \text{S}-{22}\vert < -10dB) achieves 775 MHz (2.165-2.94 GHz) or 31% corresponding to the center frequency. The Port isolation is below -28 dB in the entire bandwidth.
