Stacked 1t1r antenna system and single-input multiple-output power equalization method

Abstract

The invention discloses a laminated 1T1R antenna system, which includes a single-channel transmission and power equalization module and a single-channel broadband microstrip array antenna module. The single-channel broadband microstrip array antenna module includes a single-channel transmission and power equalization A single-channel radiation antenna connected to the module; the single-channel transmission and power equalization module is used to transmit and equalize a single-channel radio frequency signal and send it to the single-channel broadband microstrip array antenna module; the single-channel radiation antenna is used to It is used to receive the single radio frequency signal and send a constant amplitude radiation signal. The present invention uses multiple broadband microstrip array antenna modules to receive multiple antenna receiving power equalization modules to process and send single-channel radio frequency signals and then transmit radiation signals, thereby forming a consistent rectangular coverage area along the single-channel transmission direction in space. The radiated signal enables the mobile terminal to receive balanced and stable radiated signals when it moves within the coverage area of ​​the signal, and has a good receiving effect.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a stacked 1T1R antenna system and a single-input multiple-output power equalization method. Background technique [0002] With the development of mobile communication technology, Multiple-Input Multiple-Output (MIMO) technology has been applied in various mobile communication systems to improve system capacity, such as: Long Term Evolution (LTE) system And Wideband Code Division Multiple Access (WCDMA) system, etc. [0003] Since the proportion of indoor communication services is increasing, it is very necessary to apply MIMO in indoor mobile communication systems. At present, the 1T1R single-channel multi-antenna system and the single-input multiple-output power equalization method using MIMO mainly use a single-channel broadband antenna to receive a single-channel equal-amplitude and equal-frequency radio frequency signal, and then send a single-channel equal-amplitude a...

Problems solved by technology

However, due to the limitations of the structure, technology and quality of the original indoor coverage system, the coverage, amplitude, and phase of the single-channel transmission multi-antenna system radiation signals sent at the same point are inconsistent, resulting in inconsistent signal coverage of the mobile terminal in the same area during the movement process. Can receive a single-channel radio frequency signal with uneven amplitude, the reception effect is poor, and the MIMO application effect is not good
