“…The proposed antenna should satisfy high port-to-port isolation, matched co-polarisation patterns, and low cross-polarisation levels over the entire frequency bandwidth. Zhang et al [7] introduced the cylindrical polarimetric phased array radar (CPPAR) as a solution for the MPAR project. The proposed solution has many advantages, such as azimuthal scan invariant beam and orthogonal polarisation for all beam directions [8].…”

A method of beam matching between two linear polarised radiation patterns of a dual-polarised frequency scanning antenna is proposed, implemented, and tested. A meticulous phase match process between the outputs of both individual cells and the whole corresponding horizontal and vertical feed lines is carried out. To verify the simulation results and to take the coupling effect into account, the radiation patterns of an isolated column, as well as those of three columns, are measured. In agreement with the design and with the simulation results, horizontal and vertical polarisation beams with a pointing angle mismatch of less than ±0.2°within the resonant frequency bandwidth of 2.75-2.95 GHz are achieved.
