【Abstract】 By using wave concept iterative procedure(WCIP) combined with transmission lines theory analysis a three-layer ultra-wideband patch antenna was analyzed.By comparing its complexity of numeric calculation with that of classic EM field numerical algorithm,it was verified that the WCIP calculation exhibited high efficiency and speed of computation for the analysis of the multilayer circuit.Meantime,the circuit characteristic parameters of the antenna such as return-wave loss,radiation pattern and gain were calculated by using this method.It was proved by comparison with the HFSS simulation data that this method was valid in analysis of multilayer circuit.更多还原
