Abstract
A printed circuit board having an AoX antenna array and a feeding circuit is disclosed. The AoX antenna array has patch antenna disposed on a top layer of the printed circuit board, while the feeding circuit is disposed on the bottom layer. The signal traces that connect the ports of the antenna unit cells to the antenna selection switches are routed so that all are roughly equal in length with a minimal length of parallel sections between signal traces. Thus, the signal traces in the feeding circuit are created so as to minimize phase difference between signal traces and to minimize coupling. Coplanar waveguides, which utilize blind vias are used to further reduce coupling.
