Design and Simulation of a Planar Crossed-Dipole Global Navigation Satellite System (GNSS) Antenna in the L1 Frequency Band

The purpose of this research was to design and investigate the performance of a planar cross-dipole Global Navigation Satellite System (GNSS) receiver antenna to operate in GNSS L1 frequency band with multipath mitigation performance. First, a crossed-half-wavelength dipole antenna was designed to resonate centered at 1.6 GHz, and then various configurations were investigated and simulated. In an attempt to improve the antenna’s multipath mitigation performance, these various configurations included the addition of concentric rings in various numbers and sizes with the inclusion of cavity banking. Roger’s dual copper clad RO3010¿¿ material was used as a substrate for the design. The simulated cavity backing consisted of a thin block of Styrofoam¿¿ and Cumming’s RGDS-124 (microwave absorbing material) placed between the substrate and the ground plane (finite and infinite), simulated to increase the antenna performance. The prototype crossed-dipole antenna configurations were tuned and optimized based on the simulated results obtained from the Agilent’s Advanced Design System Momentum 2009U1 software. The S-parameters and radiation pattern results obtained from these simulations were compared and analyzed in MATLAB¿¿. The simulated antenna prototype performance is expected to meet the performance requirements for L1 GNSS receiver antenna.
