Study of surface waves on planar high gain leaky wave antennas
作者： Samir F Mahmoud , Yahia M M Antar

摘要: Much work has been devoted to gain enhancement of printed leaky antennas with one or more superstrates. However, little attention is paid the excitation surface waves, which can take away appreciable amount power, thus reducing net antenna gain. We present rigorous analysis for two and three dielectric layer configurations radiation power wave are derived. It shown that, certain parameters, considerably reduce efficiency and, therefore,
