Abstract
Embodiments of the present invention disclose a feeding network, and the feeding network includes: a first balun device of a first feeding subnetwork, where the first balun device is connected to a PCB positive 45-degree polarized port, which results in an equal amplitude and a 180-degree phase difference of signals at the first positive 45-degree polarized output port and the second positive 45-degree polarized output port; and a second balun device of a second feeding network, where the second balun device is connected to a PCB negative 45-degree polarized port, which results in an equal amplitude and a 180-degree phase difference of signals at the first negative 45-degree polarized output port and the second negative 45-degree polarized output port. The feeding network in the embodiments has a relatively small size and can cover multiple frequency bands.
