ABSTRACT:
In one aspect, an embodiment of the invention provides a transition from a planar substrate/chip circuit microwave transmission line to waveguide transmission media on the back of the substrate/chip. The transition enables planar waveguide fed MMW ESA architectures to be realized within the tight grid spacing required for emerging MMW ESAs.
