ABSTRACT:
A planar waveguide structure for mm-wave transmitters and receivers. The active semiconductor component elements and the planar waveguide with which they are connected of the transmitters and/or receivers are arranged on the front side of a semiconductor substrate. The rear side or surface of the semiconductor substrate is at least partially formed as an inwardly or outwardly radiating surface and is geometrically shaped such that an electromagnetic property incident or emanating radiation is altered in a predetermined manner.
