Abstract

The invention discloses a base station antenna and a feeding network device. The feeding network device includes a first substrate, a first line and a crossover network; the first line is arranged on the first substrate, and the first line includes a first transmission section and a second transmission section, and the second transmission section and the first transmission section The sections are arranged at intervals to form an avoidance area; the bridge network includes a first conductive part electrically connected to the first transmission section, a second conductive part electrically connected to the second transmission section, and a transmission line arranged above the avoidance area, and the transmission lines are respectively first The conductive part and the second conductive part are electrically connected. The feeding network device utilizes the jumper network for electrical connection, so that the arrangement between lines or electrical units is more flexible, and coupling interference and loss can be reduced. The base station antenna adopts the feeding network device, which can meet the needs of multi-band and miniaturization development under the condition of ensuring the performance of the antenna.

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...
