Aircraft Antenna Modeling, Analysis and Testing Ground Plane Effects and Considerations

With the continuing evolution of sophisticated electro-magnetics software, such as FEKO, modeling and evaluating antenna performance on full size aircraft can be accomplished with increasing flexibility. The accuracy which can be achieved is dependent on the fidelity of the base antenna and aircraft electromagnetic models. Once a given antenna or suite of antennas are modeled and evaluated, the ultimate corroboration is comparison to the actual antenna performance as mounted on an aircraft and tested. Frequently, initial ground based tests are conducted to assess the performance of an antenna. In such cases, ground plane effects can be significant and should be taken into account in the modeling and prediction process.
