According to the test data of the aircraft high frequency antenna input impedance,a more accurate electromagnetic(EM) model of the hidden high frequency airborne antenna is built.It is given a numerical simulation based on method of moment(MoM) about the composited model,which combines the high frequency antenna and the whole complex airplane electromagnetic model.In the next content,analyzed the characteristic of the antenna's radiation field in several key components of the airplane through the simulation result,and then confirms whether the field intensity is beyond the safety threshold value of the expected design.The simulation result is also feasible for aircraft electromagnetic compatibility(EMC) analysis and design of complex objects.
