Title: Feed network improving beamwidth convergence of wideband antenna
Inventor: CHEN GUOQUN
IPC: H01Q3/26
Filed: 2019-09-12
Abstract: Disclosed is a feed network improving beamwidth convergence of a wideband antenna, the network comprising: a first power divider, a time delay wire, a 90-degree electric bridge, and a second power divider. The first power divider converts a signal inputted into the feed network into two signals, changes a phase of one of the signals via the time delay wire, and then inputs said signal into the 90-degree electric bridge. The other signal is directly input into the 90-degree electric bridge. The 90-degree electric bridge converts the two received signals into two signals having the same phase and different magnitudes, outputs one of the signals to a radiating element via the second power divider, and directly outputs the other signal into the radiating element. The present invention enables, by means of the specific design of the feed network, the time delay wire to change the phase of a signal, which in turn adjusts the phase difference of input signals of the 90-degree electric bridge, and ultimately changes a magnitude allocation of the 90-degree electric bridge output signals, such that the magnitude of each radiating element changes as the frequency changes, thereby effectively improving beamwidth convergence of wideband antennas.
