Laminated 1T1R antenna system and single-input multi-output power equalization method

Abstract

The invention discloses a laminated 1T1R antenna system, which comprises a single-path transmission and power equalization module and a single-path broadband microstrip array antenna module, and is characterized in that the single-path broadband microstrip array antenna module comprises a single-path radiation antenna connected with the single-path transmission and power equalization module; the single-channel transmission and power equalization module is used for transmitting and equalizing a single-channel radio frequency signal and sending the signal to the single-channel broadband microstrip array antenna module; and the single-path radiation antenna is used for receiving the single-path radio frequency signal and sending an equal-amplitude radiation signal. According to the laminated1T1R antenna system, a plurality of broadband microstrip array antenna modules receive single-path radio frequency signals processed and sent by a plurality of antenna receiving power equalization modules and then send radiation signals, so that the consistent radiation signals in the rectangular coverage range formed along the single-path transmission direction are formed in the space, and the mobile terminal can receive balanced and stable radiation signals when moving in the signal coverage range, and a good receiving effect is achieved.

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
