1. A feed network for feeding two adjacent radiation units in the same row in an antenna array, the feed network comprising:
a printed circuit hoard;
two microstrip power dividers arranged on the printed circuit board, a microstrip structure of each of the two microstrip power dividers configured to realize impedance matching, and input ends of the two microstrip power dividers configured as two input ends of the feed network; and
two microstrip combiners arranged on the printed circuit board, two input ends of each of the two microstrip combiners respectively connected to one output end of each of the two microstrip power dividers, and output ends of the two microstrip combiners configured as two output ends of the feed network, so as to realize a multiple-input multiple-output feed network.
