GPS antenna characterization in an anechoic chamber

This paper is part of a continuing work with the FAA to develop an antenna testing methodology to characterize antenna performance in a multipath environment. This paper presents a case study to determine the characterization of two GPS antennas of varying performance in real world deployment. Power and phase measurements were acquired at the Wireless and Electromagnetic Compliance and Design (WECAD) Center, at the University of Oklahoma-Tulsa. Measurements were performed in a semi-anechoic chamber to characterize two broadband antennas. It is demonstrated that power and phase measurements were not sufficient to differentiate between different performing antennas in a multipath environment.
