Comprehensive modeling of an embedded GPS patch antenna

Abstract

This work deals with the modeling of embedded antennas on aircrafts. A standard GPS patch antenna is chosen as a reference case to illustrate a comprehensive work from design to evaluation. To fit the topic of the special session, we focus on the disturbances on both impedance matching and radiation patterns induced by embedding in a cavity. Finally we explain how to adapt the antenna definition in order to compensate the coupling with its environment.
