Abstract

Phased array antennas are used in applications where beam steering is required. However, especially for large tilt angles, the polarization purity of such antennas can be compromised, which leads to a significant degradation of the signal-to-noise ratio. To mitigate this effect, we consider a link working with circularly polarized waves in the Ka band. The transmission side has beam steering functionality. The receiver antenna elements have right- and left-hand circular polarization ports, and each port is equipped with a variable gain and phase shift elements, whose values are selected to provide optimum cross-polarization discrimination.
