ELECTRICALLY LONG RECTANGULAR PATCH ANTENNA FED BY MEANDERING PROBE WITH WIDEBAND AND HIGH GAIN CHARACTERISTICS

摘要

A linearly polarized electrically long rectangular patch antenna fed by a meandering probe is presented. By increasing the width of a patch antenna to 1.05λ{sub}0, the gain of the antenna can be increased. The antenna has an impedance bandwidth of 26% (SWR < 1.5), a gain of 11.2 dBi, and a crosspolarized level less than -15 dB across the operating bandwidth.
