Circular patch antenna with integrated arc slots. In one embodiment, the circular patch antenna includes a top dielectric patch and a bottom dielectric patch. The top dielectric patch includes a first plurality of apertures while the bottom dielectric patch includes a second plurality of apertures. At least a portion of the first plurality of apertures and the second plurality of apertures are aligned with one another when the top dielectric patch is positioned over the bottom dielectric patch. A flex printed circuit board (PCB) is positioned between the top dielectric patch and the bottom dielectric patch and includes a plurality of arc slots, each of the plurality of arc slots are positioned between the first and second plurality of apertures and an external periphery of the flex PCB. Methods of operating the circular patch antenna as well as systems that incorporate the circular patch antenna are also disclosed.

An antenna array may include a plurality of printed circuit boards (PCBs) oriented in a stacked arrangement, parallel to and spaced apart from one another. Each of the PCBs may include a linear array of antenna elements, which cooperate with the linear arrays of antenna elements on other PCBs to form a two-dimensional array of antenna elements. The PCBs may be supported at one end by a common backplate in a cantilevered manner, with the linear arrays of antenna elements located near the free end of the PCBs. The PCBs may include a thicker portion and a thinner portion, and the thinner portion may include a heat sink or other thermal dissipation structure.
