Loop-dipole antenna modeling using the FEKO code

A study was done to optimize the design of a loop dipole antenna over a broad frequency range (0.5 - 2 GHz) using the FEKO method of moments code. Variations to the design were modeled as well as the performance of the antenna in an array. The modeling was compared to anechoic chamber data. The fields generated by the FEKO code were also input to a GTD (geometric theory of diffraction) code as an antenna pattern to model the multipath effects caused by mounting the antenna onto an aircraft.
