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 to ensure its suppression a considerable effort has to be made. This paper presents a new method to solve this problem by using striplines with two different dielectric substrates on the two sides of its center strip. 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 the parallel plate mode. A sixteen element microstrip array was designed and tested to demonstrate this new concept.
