Abstract
A multilayer printed radiator for a phased antenna array of a user terminal for Ka-band satellite communications is considered. The design of the radiator is described and the results of calculations of the radiator model are presented. The radiator operates on circular polarization in the frequency range of 29–30 GHz and has a scanning area in the form of a cone with a solid angle of ±65 degrees. To reduce the level of cross-polarization, groups of four radiators with sequential rotation of 90 degrees are used. The results of calculations for such a group of radiators in the Floquet channel condition are presented.
