Abstract
According to one embodiment, an RF front end includes an antenna array that is attached to a PCB. A structure is attached to the PCB. The structure has a plurality of concentric rings to enclose an antenna array on the PCB. Each of the plurality of concentric rings has a vertical portion attached to a ground plane of the PCB through a substrate of the PCB, and a planar strip attached to the vertical portion at an end that is opposite of the ground plane.
