4.8GHz-6.5GHz 21dBi dual polarization sector antenna introduction

From:Zhaoqing Xiangjiasheng Technology Co., Ltd     Release time:2021-03-24

Overview: This 4-port 90-degree dual oblique polarization + 45°/ -45° polarization sector antenna has a universal dual-radio installation system, which can connect two Ubiquiti Networks RocketM5® or Rocket®Prism 5AC, Mimosa C5c, Cambium ePMP™ 1000 or TP- Connect WBS-510 directly to the antenna. The antenna provides 4 separate ports, two +45° polarization and two -45° polarization, and all ports support 4.9 GHz-6.5 GHz operation.

Dual-polarization antenna is a new type of antenna technology, which combines +45° and -45° polarization directions orthogonal to each other antenna and works in the transceiver duplex mode at the same time, so its most prominent advantage is to save a single directional The number of antennas of the base station.


Dual-polarization antenna is a new type of antenna technology that combines +45° and -45° polarization directions orthogonal to each other antenna and works in the transceiver duplex mode at the same time, so its most prominent advantage is to save a single directional The number of base station antennas; generally, the directional base station (three sectors) of the GSM digital mobile communication network uses 6 antennas, and each sector uses 2 antennas (space diversity, one transmitter and two receivers). If dual-polarized antennas are used, each Only one antenna is required for each sector; at the same time, due to the polarization orthogonality of ±45° in dual-polarized antennas, the isolation between +45° and -45° two antennas can meet the requirements of intermodulation pair antenna isolation Degree requirements (≥30dB), so the space between dual-polarized antennas only needs 20-30cm; in addition, dual-polarized antennas have the advantages of electronically adjustable antennas, and dual-polarized antennas are used in mobile communication networks. Like the antenna, it can reduce call loss, reduce interference, and improve the quality of service of the entire network. If a dual-polarized antenna is used, because the dual-polarized antenna does not have high requirements for erection and installation, there is no need to requisition the land to build a tower, only a 20cm diameter iron post is needed, and the dual-polarized antenna is fixed on the iron post according to the corresponding coverage direction That is, it saves capital construction investment, and at the same time makes the layout of the base station more reasonable, and the site selection of the base station is easier.
