Load balancing of dual-polarized antennas
There is provided a dual-polarized N/2-column antenna arrangement. The antenna module arrangement comprises a coupler module. The coupler module is arranged to direct a first summation of energy from signals from a first distinct set of power amplifiers of an N-channel radio to a first single output port connected to a first polarization of a first column of the dual-polarized N/2-column antenna arrangement. The coupler module is arranged to direct a second summation of energy from signals from a second distinct set of power amplifiers of the N-channel radio to a second single output port connected to a second polarization of a second column of the dual-polarized N/2-column antenna arrangement.
