Simulation results show that the structure has excellent resonant characteristics in the range of 3.34GHz-1.59GHz, and has certain sensitivity for the change of the capacitance value,so it can achieve electrical controllable in the frequency band. The simulation results also show that this structure can satisfy characteristics for multiple perspectives in the whole plane, and be suitable to reduce radar cross section,when it is used on radomeofweapon systems in practical war.

Introduction The application of Electronic surveillance technology of modern warfare in aircraft, missiles and other factors in the air, largely determines the outcome of the war, reduces the radar cross section (RCS) of weapon systems, which is an important mean of anti- reconnaissance to be ta
