Abstract
The design of a microstrip antenna which operates at the GPS L1 band is presented in this paper. The miniaturization and the right-hand circular polarization (RHCP) is obtained through a square-ring patch and truncated corners in which, respectively. The simulated results indicate that the impedance matching is excellent, the antenna has the characteristic of wide-angle circular polarization, and the radiation patterns of RHCP are excellent; In a wide elevation angle range, the RHCP level is at least 15dB higher than that of LHCP, which has a good suppression of interference from cross-polarization and multipath effect. Compared with the conventional GPS microstrip antenna with the same material, the characteristics of the proposed antenna are enhanced, the whole size is reduced, the area of the radiating patch is reduced by 26%, meanwhile,the cost of the antenna’s substrate material is low, which satisfies with the requirements of GPS receiver for miniaturization, low-cost and compactness.
