3.2.3 Direct radiation from a PCB which is parallel to a metallic cover plane at an electrically short distance

This parallel plane structure radiates from the slots and apertures at the open edges of the parallel plane structure, established by the PCB ground plane and the metallic cover plane. An efficient method, based on a cavity model, is developed in this work to describe this radiation. The radiated field from the structures on the PCB is scattered at the parallel planes and, thus, only the cavity mode fields can propagate to the edges. Therefore, the cavity model, which considers the coupling of PCB structures to the cavity field, describes the radiated emission accurately. An efficient model for predesign investigations of the free space radiation of a rectangular enclosure with a slot on one edge is presented in Chapter 7.
