Abstract
In this paper, a new circular polarization microstrip antenna for satellite navigation receiving is proposed. The antenna layout employs electromagnetic bandgap structures over a Rogers TMM10i (\( \varepsilon_{r} = 9.8 \)) substrate to achieve the effective permittivity enhangcement. At the edge of the radiation patch, four coupled shorting strips are designed to achieve the goals of size miniaturization and better circular polarization property. The measured and simulated results show that the effective bandwidth can cover the whole B3 band. The axial ratio for the zenith is less than 2 dB and less than 8 dB at the elevation 20°. The proposed antenna fabricated over a substrate with the size of 25 mm * 25 mm * 5 mm that has approximately 45% size reduction compared with the conventional microstrip antenna over the same substrate. The measured realized gain is 3.3 dBic over a 80 mm * 80 mm ground plane with 24 MHz 3 dB realized gain bandwidths. The proposed receiving antenna has important values in satellite navigation.
