Abstract
A printed circuit board (PCB) antenna assembly having a metal shroud and a method of making the same are presented. The shroud reduces radio frequency (RF) interference from the rear of the PCB antenna while not introducing unwanted nulls in front of the antenna. The metal shroud has a back panel and two angled side panels and is set so that the back panel is parallel to the PCB antenna and set at a determined distance from the PCB antenna. The shroud can be formed by applying a metallized paint to a non-conducting cover with properly oriented surfaces.
