N2 - Multi-beam multiplexing design based on the interleaved subarray architecture can be achieved by uniform linear arrays (ULAs) consisting of isotropic antennas in previous works. By considering the polarisation information of a signal, the crossed-dipole array is employed, where each antenna is associated with two complex-valued weighting coefficients. To reduce the implementation complexity of the system, when a large number of crossed-dipole antennas are available, we may not need to employ all of them and a subset of the available antennas may be sufficient for a specific beamforming scenario. For this purpose, two design methods are proposed to select the best set of crossed-dipole antennas or dipoles. Designed examples are provided to verify the effectiveness of the proposed methods.
