Abstract
A circularly polarized Global Positioning System (GPS) antenna using parasitic lines, in which circular polarization is implemented to improve the efficiency of the reception of satellite signals by an antenna. For this, a circularly polarized GPS antenna using parasitic lines according to an embodiment includes a substrate, a radiating patch formed on a top of the substrate, a parasitic line part formed on the top of the substrate and disposed to be spaced apart from the radiating patch, thus implementing circular polarization characteristics by inducing reverse current, a ground plate formed on a bottom of the substrate, and a feeding via formed through the substrate and configured to electrically connect the ground plate to the radiating patch.
