Several Global Navigation Satellite Systems are including the L5 frequency to add additional services. The RTCA Subcommittee 159 (SC-159), World Group (WG-7) is involved in this process and has concerns about the impact that asymmetric ground planes (i.e., aircraft fuselage structures) may have on the performance of the GNSS antenna, most notably the radiation pattern and axial ratio (AR). In this thesis two techniques were investigated to control both radiation pattern and AR of an L5 antenna. To control the radiation pattern a four-fed circular patch antenna was modeled and simulated using a high-fidelity computational electromagnetic model (CEM). Phase and amplitude manipulation of the feeds were used to control the radiation and AR characteristics. This approach has a major advantage by controlling the radiation characteristic to allow for isolation of interfering signals. Control over the asymmetry of a rectangular patch antenna improves the AR on an asymmetrical rectangle ground plane. Several different patch and ground plane shapes were used to demonstrate these advantages: 1) a circular patch antenna with a circular ground plane, and 2) a rectangular patch antenna (element and substrate) with a rectangular ground plane.
