Abstract
Apparatuses, methods, and systems for an antenna assembly, are disclosed. One apparatus includes a multiple layer printed circuit board (PCB), a dielectric plate, and antenna elements. The PCB includes antenna excitation feed elements, wherein the antenna excitation feed elements are located on a layer of the PCB. A second surface of the dielectric plate is affixed to a first surface of PCB forming gaps adjacent each of the antenna excitation feed elements, wherein a dielectric constant of the dielectric plate, a thickness of the dielectric plate, and a thickness of the gaps are selected based on an operating frequency of wireless signals communicated through the antenna assembly, and based on RF (radio frequency) characteristics of the PCB. Each of the antenna elements are affixed to a first surface of the dielectric plate.
