Abstract
A printed circuit board ('PCB') including a substrate integrated waveguide ('SIW') formed using two ground planes representing the top and bottom walls of the waveguide, tightly pitched ground vias to act as two side walls and two back walls, and a pair of monopole antennas placed at each end of the SIW acting as signal feeding/receiving structures is disclosed. The waveguide dominant mode cut off frequency is determined by the spacing between the two side walls. Within each monopole antenna pair, the first monopole antenna operates at a first frequency while the second monopole antenna operates at another frequency. For each monopole antenna pair, the first monopole antenna and the second monopole antenna are located in the SIW at a distance from the back wall optimal for each operating frequency.
