The excitation of the parallel plate mode in stripline configurations is a serious concern in the design of multilayer feeding networks. Using either probes or slots as means of power transfer between adjacent layers, this parasitic mode is always excited, and a considerable effort has to be made to assure its suppression. This paper presents a new method that uses striplines with two different dielectric substrates on the two sides of its center strip to solve this problem. By using the asymmetric stripline in the vicinity of a source of excitation, a surface wave is excited at a significantly weaker level rather than at the parallel plate mode. A 16-element microstrip array was designed and tested to demonstrate this new concept.
