摘要
An aperture coupled, single fed, microstrip line feed for a circularly polarized patch antenna is provided that can transmit transmissions with a low profile, wide impedance, and axial ratio bandwidths. The circularly polarized patch antenna includes a double sided printed circuit board with a non-linear slots etched into a ground plane of one side of the printed circuit board, with a printed microstrip line printed on the opposite side of the printed circuit board. The microstrip line can be hook shaped and intersect each of the slots. The non linear slots can be radially arranged around a locus or area on the circuit board. A metal patch can placed above the ground plane and electromagnetic waves emanating from the microstrip line can couple to the patch through the non-linear strips and excite the patch such that it radiates an electromagnetic transmission
