Minkowski Fractal Circularly Polarized Planar Antenna for GPS Application

Abstract A novel fractal based circularly polarized GPS antenna is designed to meet the bandwidth requirements of satellite receiver (30 MHz) operating at a frequency of 1.575GHz. To achieve the circular polarization a truncated corner square patch technique is adopted. A 3-dB axial-ratio of 2.3405dB is obtained at the operating frequency. The gain obtained is 0.3694 dB.
