Device, method, antenna module and system for detecting mismatch degree of dual-polarized antenna

Abstract

The invention discloses a device and a method for detecting a mismatch degree of a dual polarized antenna, an antenna module, and an antenna system, for reducing the requirement on monitoring loss value mismatch of the dual polarized antenna. The device for detecting the mismatch degree of the dual polarized antenna comprises a radio frequency identification label antenna module which can form a radio frequency identification label vertical antenna and a radio frequency identification label horizontal antenna; a detection module used for detecting first power and second power of polarized signals separately output by the radio frequency identification label vertical antenna and the radio frequency identification label horizontal antenna based on wireless signals transmitted by the dual polarized antenna; a judgment module used for judging whether the difference between the first power and the second power exceeds a preset threshold; and a confirmation module used for confirming that the dual polarized antenna is mismatched when the difference between the first power and the second power exceeds the preset threshold. According to the device, the method, the module and the system provided by the invention, the requirement of monitoring the loss value mismatch of the dual polarized antenna is reduced.

Description

technical field [0001] The invention relates to the field of wireless propagation technology, in particular to a device, method, antenna module and system for detecting mismatch degree of dual-polarized antennas. Background technique [0002] With people's increasing demand for mobile Internet, mobile users' demand for network quality and traffic continues to increase. Many important indoor places need to use indoor distributed antenna feeder systems to enhance coverage and increase capacity. [0003] As a special type of indoor antenna, the dual-polarized antenna has two RF input ports, which can send vertically polarized and horizontally polarized signals to enhance indoor coverage and peak rate. However, for a dual-polarized antenna, the mismatch of the loss values ​​of the two RF feeder channels will directly lead to poor coverage of the dual-polarized antenna. Therefore, it is necessary to monitor the mismatch of the loss value of the dual-polarized antenna, and adjust...

Problems solved by technology

[0004] In the prior art, the loss value mismatch of the dual-polarized antenna is monitored by integrating an RFID tag antenna inside the dual-polarized antenna. To monitor the mismatch of the loss value of the dual-polarized antenna, there is a strict requirement on the location of the label, and it is not suitable for large-scale deployment.
