Impact of a cover layer to high impedance ground plane band-gap
介质覆盖对高阻表面带隙的影响

In this paper a kind of high impedance substrate surface covered with different dielectric layer is analyzed by periodic moment method, their band-gap diagrams are described. Meanwhile, the propagating property of surface wave of the high impedance ground plane with different dielectric covering is tested, the results of theoretic analysis are validated. Our results can be helpful for the design of high impedance ground plane with a dielectric cover layer.
