Patent abstract
GNSS signals are centered around two bands, L1 and L2, and antennas must cover both these bands for good RTK performance. GPS is at a lower frequency in both bands than the Russian GLONASS system. What is described herein is a method of constructing a low profile dual frequency wideband antenna with excellent polarization and signal reception for both GPS and GLONASS. This technique minimizes the impact of tolerances of the dielectrics, thicknesses and tuning by optimal construction.
