Abstract
This paper presents a novel calibration technique for circularly polarized active antenna array with improved axial ratio and polarization-agile systems. The proposed algorithm deals with the problem of calibration of active antenna arrays, proposing a calibration technique that can be implemented in offsite or on-site process depending on the system calibration and control design. The proposed calibration technique starts with the implementation of a complex circular polarization feeding network with the capability to change the response of each of the polarization circuits with signal attenuators. The expansion of equations of the proposed calibration algorithms is also presented. This algorithms deal with the compensation of mutual coupling effect and together with gain, phase and location errors.
