Abstract
An antenna element includes a multi-layer printed circuit board (PCB). The PCB includes a top metal layer, a second metal layer, a third metal layer, and a bottom metal layer. Dielectric layers are positioned between each of the metal layers. A thickness of the PCB is defined by a total thickness of the layers. The top metal layer, the second metal layer, and the third metal layer are all of different lengths. The second metal layer and the third metal layer include a plurality of slots formed therein. Each of the plurality of slots having a size and a position tuned to a central frequency. The antenna array of the plurality of antenna elements are arranged oriented in two orthogonal polarizations.
