Abstract

The invention discloses a base station antenna and a feed network device. The feed network device comprises a first substrate, a first line and a bridging network; the first circuit is arranged on thefirst substrate and comprises a first transmission section and a second transmission section, and the second transmission section and the first transmission section are arranged at an interval to form an avoidance area; and the bridging network comprises a first conductive part electrically connected with the first transmission section, a second conductive part electrically connected with the second transmission section, and a transmission line arranged above the avoidance area; and the transmission line is electrically connected with the first conductive part and the second conductive part respectively. According to the feed network device, the bridging network is used for electrical connection, so that the arrangement between lines or electrical units is more flexible, the coupling interference can be reduced, and the loss is reduced. The base station antenna adopts the feed network device, and can adapt to the requirements of multi-band and miniaturized development under the condition of ensuring the antenna performance.

Description

technical field

[0001] The invention relates to the technical field of mobile communication, in particular to a base station antenna and a feeding network device. Background technique

[0002] As an important part of the wireless communication system, the base station antenna plays a pivotal role in the communication network. With the continuous innovation and progress of mobile communication technology, the fifth generation of mobile communication technology (5G) is also in full swing. The fifth-generation mobile communication technology has the characteristics of ultra-low delay, high transmission rate, larger system capacity, and more stability. At the same time, in order to meet the needs of construction, base station antennas also need to develop in the direction of multi-band and miniaturization.

[0003] The base station antenna needs to satisfy both multi-band and antenna miniaturization development, so that the lines of the feeding network are arranged in a compact...
