Summary:A method to improve the bandwidth of classical E-shaped circularly polarized patch antenna is proposed in this paper. By adding metallic fragments to the long slot of the E-shaped patch antenna and representing the fragments numerically in a matrix, the computer can automatically generate the antenna geometry and finds the best solution for a wider axial ratio (AR) bandwidth through Monte Carlo method. The simulation results show that the fragmental E-shaped patch antenna has much wider AR bandwidth (15.89%) than the conventional E-shaped patch antenna (7.28%) with the same size.
