FEEDING NETWORK, ANTENNA AND DUAL-POLARIZED ANTENNA ARRAY FEEDING CIRCUIT |
摘要 |
Embodiments of the present utility model 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, connected to a PCB first positive 45-degree polarized output port by using a first microstrip, and connected to a second positive 45-degree polarized output port by using a second microstrip, 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, connected to a PCB first negative 45-degree polarized output port by using a third microstrip, and connected to a second negative 45-degree polarized output port by using a fourth microstrip, 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 embodiments of the present utility model further provide an antenna and a dual-polarized antenna array feeding circuit. The feeding network in the embodiments has a relatively small size and can cover multiple frequency bands. |
