One of the properties of high impedance surface is that the phase of the reflection wave by the surface is zero.A high impedance surface was used as antenna reflecting surface. A dipole antenna was designed as radiation source. Simulation demonstrated that when the patches number of surface changed the radiation pattern changed and the gain varied also. The distance between antenna and the reflection face varied the radiation pattern also changed. Controlling the number of cells or distance between antennas from reflection plane the gain of antenna can be improved.
