Abstract
A feed network includes a first power divider, a delay line, a 90° electric bridge and a second power divider. The first power divider converts an input signal of the feed network into a first signal and a second signal, transmits the first signal to the delay line, and transmits the second signal to the 90° electric bridge directly. The delay line changes a phase of the first signal and transmits the first signal to the 90° electric bridge. The 90° electric bridge converts the received first signal and the received second signal into two signals having a same phase but different amplitudes, transmits one of the two signals to the second power divider, and outputs the other one of the two signals to a first radiator directly. The second power divider outputs the one of the two signals to a second radiator.
