Patch antenna, element thereof and feeding method therefor

摘要

Various embodiments of a patch antenna, element thereof and method of feeding therefor are described. In general, the patch antenna is configured to generate orthogonal beams and comprises an array of patch elements each contributing to the orthogonal beams and comprising one or more resonators, a base reflector, and a dual feed mechanism. The dual feed mechanism generally comprises two pairs of feeding elements, each one of which comprising substantially balanced feeds configured to drive a respective one of the orthogonal beams via substantially anti-phase capacitive coupling.

1. A patch antenna element for generating orthogonal beams comprising one or more resonators, a base reflector, and a dual feed mechanism, said dual feed mechanism comprising two pairs of feeding elements capactively coupled to at least one of the one or more resonators via substantially coplanar anti-phase capacitive coupling, each of said pairs comprising substantially balanced feeds configured to be driven via respective anti-phase signals to respectively generate the orthogonal beams.
