The first element set includes at least three first elements arranged in a row. The second element set includes at least three second elements arranged in a row. The at least three first elements of the first element set and the at least three second elements of the second element set are independent of each other. The feed network includes a first feed network and a second feed network. The first feed network includes a first cable set and a first power divider. The second feed network includes a second cable set and a second power divider.

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.
