Full-closed loop automatic tuning control device and method for improving stray isolation degree between antennas

Abstract

The invention provides a full-closed loop automatic tuning control device for improving stray isolation degree between antennas, relates to the technical field of communication and particularly relates to an antenna. The full-closed loop automatic tuning control device comprises a plurality of communication components, wherein each communication component comprises an antenna, a transceiver and an antenna transfer switching module, at least one communication component comprises a tuning module, and the antenna transfer switching modules are directly connected with the antennas or connected with the antennas through the tuning module; the antenna transfer switching modules realize signal connection with transmitting ends and receiving ends of the transceivers through switching actions; the transmitting ends of the transceivers are connected with a standing wave detection module, and the receiving ends of the transceivers are connected with a signal detection module. By monitoring the state of reflection power, the radiation efficiency of the antennas is not reduced; meanwhile, by detecting the strength of received signals, the isolation degree between the antennas is known, and the tuning module is further adjusted to continuously enable the sending efficiency and the stray isolation to achieve the best balance; thus, the requirements of mobile terminals, namely the two-way antennas on radiation performance are met, and the anti-interference capability between systems is improved.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to an antenna. Background technique [0002] Due to certain needs, the mobile phone needs to have a dual-pass function, such as talking on the one hand and data transmission on the other hand. However, with the reduction of the size of the mobile terminal, and in order to meet the wireless transmission of different protocols, several antenna devices must be installed in a limited space, which makes the design of the antenna more difficult, and the solution to the spurious interference between the antennas is becoming more and more difficult. more important. Therefore, how to reduce the stray coupling between the two antennas is a difficult point and an important point in solving the dual-pass performance. Contents of the invention [0003] The object of the present invention is to provide a fully closed-loop automatic tuning control device for improving the spurious isola...
