Abstract
Disclosed is a feed network, which includes a printed circuit board, two microstrip power dividers and two microstrip combiners, and the two microstrip power dividers and two microstrip combiners arranged on the printed circuit board. A microstrip structure of each microstrip power divider is configured to realize impedance matching. Input ends of the two microstrip power divider are configured as two input ends of the feed network, two input ends of each microstrip combiner are respectively connected to one output end of each microstrip power divider, and output ends of the two microstrip combiners are configured as two output ends of the feed network, so that a multiple-input multiple-output feed network is realized. Therefore, when the feed network is applied to a base station antenna, all the radiation units are arranged in a linear matrix to achieve the effect of miniaturization of the base station antenna.
