Minkowski Fractal Boundary Patch Antenna for GPS Application

A Minkowski fractal boundary patch antenna is nominated for L1 band GPS applications. The Minkowski fractal curves are substituted at the sides of the square patch for size miniaturization. The main objective of the proposed work is to design compact GPS antenna by employing fractal concept. The Minkowski iteration order 1 and iteration order 2 are studied. The proposed antennas are simulated using HFSS simulation tool. An impedance bandwidth of 6.9 % (1.52-1.63 GHz) and 5 % (1.53-1.61 GHz) are achieved with the iteration order 1 and iteration order 2 Minkowski fractal antennas.
