Comparison of radiation pattern modeling methods for GPS controlled reception pattern array

Abstract

A four element dual-linear polarized pin-fed patch antenna array is modeled as a controlled reception pattern array for anti-jam GPS applications. Full-wave electromagnetic simulation is used to refine the model and account for parasitic effects such as mutual coupling. The effects of using full-wave simulated antenna radiation patterns rather than analytically calculated patterns for calculation of weight vectors to implement null steering are explored.
