Research on the airborne antenna layout of UAV with ultra-broadband EMP source

In order to overcome the mutual interference between the Unmanned aerial vehicle (UAV) airborne antenna to reduce the coupling, airborne antennas are modeling, and uniform geometrical theory of diffraction (UTD) equivalent source technology combined with Feko simulation software was adopted to optimize the antenna layout simulation. The simulation results are consistent with the experimental results. The total coupling is only 2.85. This greatly saves the test time. This method can be used to predict and evaluate the coupling degree of the airborne antennas quickly and accurately, and can be of great significance to the experiment.
