Problems solved by technology

[0003] However, in the existing MIMO antenna system, when the antenna is poorly fastened on the antenna connector and the open circuit occurs, the power amplifier (power amplifier, referred to as PA) will generate strong reflection at the antenna connector, and the peak voltage that occurs during the open circuit is easy to causing PA damage

Embodiment Construction

[0060] The present invention will be described in further detail below with reference to the accompanying drawings and examples.

[0061] see figure 1 , figure 1 It is a block diagram of a MIMO antenna system according to an embodiment of the present invention.

[0062]In this embodiment, the control module 110 is configured to send radio frequency signals to the antenna, receive radio frequency signals from the antenna, and control the entire MIMO antenna system. The control module 110 may be a control circuit composed of a central processing unit, a radio frequency transceiver and other circuits. The control module 110 sends the radio frequency signal and the control signal to the power amplifier 120. The power amplifier 120 refers to an amplifier that can generate maximum power output to drive a load under a given distortion rate condition. The power amplifier 120 is electrically connected to the control module 110 and the control switch 140 respectively, and the control...

Abstract

The invention provides a detection and alarm device, and an MIMO antenna system applied in the detection and alarm device, wherein the detection and alarm device is characterized in that by coupling afirst transmission line and a second transmission line to detect whether or not there is antenna connection, and after detection results are output, a control sign is output by a comparison module and a switch module to control operation of an alarm module, a power amplifier and the system. The MIMO antenna system further includes a control module, the power amplifier, a low noise amplifier, a control switch, and an antenna apart from the detection and alarm device. The invention further provides a method of detecting antenna link state, which is characterized by sending out a control instruction to switch off the power amplifier and alarming when it is detected that the antenna is not connected in a fastened mode, and therefore the device is prevented from being damaged and cost is saved. The detection and alarm device and the MIMO system have the advantages of simple structure, high reliability, and steady application to various wireless communication applications.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a Multiple Input Multiple Output (Multiple Input Multiple Output, MIMO for short) antenna system. Background technique [0002] At present, with the continuous development of wireless communication technology, people have higher and higher requirements for wireless communication, and the traditional antenna system can no longer meet people's requirements for channel capacity. The use of MIMO technology can significantly increase the channel capacity, and by using multiple antennas at the transmitter and receiver at the same time, it can greatly improve spectrum utilization and improve transmission efficiency. [0003] However, in the existing MIMO antenna system, when the antenna is poorly fastened on the antenna connector and the open circuit occurs, the power amplifier (power amplifier, referred to as PA) will generate strong reflection at the antenna connector, an...
