Abstract :
The characteristics of a microstrip patch antenna with stacked parasitic elements, metallic strips, and superstrate have been investigated in terms of antenna gain. To enhance the antenna gain, it is important to suppress undesirable surface waves. In this paper, we propose a new parasitic metallic bar to reduce the propagation of a surface wave. Simple and analytic solutions of the surface wave scattering from a metallic bar on a grounded dielectric-slab are obtained using the mode-matching method.
