Abstract

An analysis is developed for a patch antenna coupled to a transmission line. The coupling port is placed on the same side and the opposite side of the feeding end. A transmission line method is used to model the circuit. Experimental results are presented to verify the simulated results. Whether the coupling port is placed on the same side or the opposite side of the feeding end, the coupled power levels from the patch to the transmission line are almost the same. The coupling characteristics as a function of the gap and length variations are also identical for these two configurations.
