Novel design of compact circularly polarized shorted annular stacked patch antenna has been proposed for global navigation satellite system in this study. The antenna has been designed to operate for the satellite navigation frequencies, including GPS, GLONASS, Galileo and Compass (1100-1600MHz). Dual-layer strip lines that being composed of one broadband 180 degrees hybrid and two wideband 90 degrees hybrids are introduced as feeding network. As a result, the antenna has a 50.8% 10-dB return loss bandwidth from 1.1 to 1.85GHz, and 45.5% 3-dB axial ratio bandwidth from 1.07 to 1.7GHz, respectively. The designed antenna occupies a compact size of 70mmx70mmx28.5mm. In this study, shorted annular stacked patch is introduced to obtain stable gain bandwidth, broad beam width characteristics, and good axial ratio at low elevation.
