Abstract

In this paper, a patch antenna with an PBG (photonic band-gap) structure was studied by FEM method, and the theory of PBG structure was introduced. The Ansoft HFSS is used for the simulation. A comparison between the conventional patch antenna and the new PBG antenna is given. It is shown that the surface waves propagating along the substrate surface can be suppressed by the periodic structure due to the influence of its forbidden band. As a result, the patch antenna based on the PBG structure has a higher gain and a wider bandwidth in comparison with the conventional patch antenna.
