Abstract: In order to broaden the bandwidth of a microtrip patch antenna, a broadband two-port feeding technique based on the principle of reactance compensation is suggested. The principle and some design guidelines are presented; the calculation model of a practical configuration as well as its parameter optimization is demonstrated, followed by several kinds of test models and their experimental results. It is shown that this technique enables the VSWR bandwidth to be broaden to 2-3 or more times than that of the conventional design for both linear and circular polarzation operatons. -
