Theoretical Analysis and Simulation Verification of Non-regular Circularly Polarized Array Antenna

To address the gain loss issue of non-regularly arranged circularly polarized array antennas, this paper proposes a feeding method that compensates for the installation angle of the array elements by adjusting the feeding phase based on the electric field intensity synthesis of circularly polarized array antennas. The correctness of the theoretical analysis is verified through the simulation of a three-element array calculated using commercial software. This feeding method can be generalized to other non-regularly arranged circularly polarized arrays with arbitrary forms.
