Comparison of NEC simulation and measurement methods for the solution of coupling between airborne antennas
Many simulation methods have been developed for the solution of Electromagnetic problems. One of the best ways to evaluate the accuracy of these methods is comparing them with actual measurements. In this study, the optimization of the electromagnetic interference (EMI) induced by two aircraft on-board VHF-UHF transreceiver antennas is implemented. The EMI reduction is implemented by varying the antenna positions and orientations. The transreceiver antennas are modelled as single monopole antennas therefore the problem is reduced to antenna-to-antenna coupling optimization. The Method of Moments (MoM) is selected for the EMI analysis and the continuous parameter Genetic Algorithm (CPGA) is chosen for the optimization method. The results of the numerical analysis are verified by the measurement on a 1:10 scaled model in an anechoic chamber.
