Abstract
This paper presents the design of a circularly polarized microstrip antenna for global positioning system (GPS). This single-feed and single-layer antenna works at the L1 (1559-1615MHZ) frequency band for civil use of GPS. There are two pairs of symmetric rectangular slots and circular slots in the diagonal directions respectively. The right-handed circular polarization (RHCP) is obtained by using the slight difference between the rectangular and circular slots. Four E-shaped shots are embedded on the ground plane to improve the antenna gain. The results show that the antenna gain has increased some 0.83dB. The -10dB impendence bandwidth is 39.3MHz and the 3dB axial ratio is 14.9MHz. It is obvious that this antenna can be used in GPS.
