CPW Feed Patch Antenna for GPS Applications

In this paper, the authors are proposing a CPW-Fed patch antenna. This paper presents the design of rectangular patch micro-strip antenna for the frequencies at L1 (1.67 GHz to 1.90 GHz) and L2 (2.65 GHz to 3.05GHz). The simulation is done by using the HFSS software, which is a full-wave simulation tool, based on the method of moments the bandwidth of the proposed antenna reaches about 230MHz & 400MHz with the return loss of about -30dB & -28dB respectively over the chosen frequency spectrum.
