In this paper, a GPS (Global Positioning System) patch antenna using 90 degree phase shifter for RHCP and broadband AR(Axial Ratio) bandwidth was designed and implemented. We provided two patches as a FR-4 patch and a 1.5mm thickness thin ceramic patch with 90 degree phase shifter. 90 degree phase shifter is fed to each patches to achieve CP (Circularly Polarization) radiation. SMD by chip elements was applied to 90 degree phase shifter. VSWR measurement showed within 2 : 1 over the whole design band, and 3dB AR bandwidth was 205MHz. Antenna gain and efficiencies were measured as 1.36-2.75dBi and 15.11-25.3%, respectively.
