Dual frequency circularly polarised proximity-fed microstrip antenna.
The design feasibility of a three-layer proximity coupled fed microstrip antenna structure for dual frequency operation with circular polarisation is demonstrated. As a proof of concept an antenna designed for operation at the two GPS frequencies is fabricated. The measured results show that low axial ratios can be obtained at both frequency bands.
