Technical Field

The invention relates to the technical field of communication, in particular to a laminated 1T1R antenna system and a single-input multi-output power balancing method.

Background

With the development of mobile communication technology, single-input Multiple-output (MIMO) technology has been applied to various mobile communication systems to increase system capacity, such as: a Long Term Evolution (LTE) system, a Wideband Code Division Multiple Access (WCDMA) system, and the like.

As indoor communication traffic is heavier and heavier, it is very necessary to apply MIMO in an indoor mobile communication system. At present, a 1T1R single-path multi-antenna system and a single-input multi-output power equalization method applying MIMO mainly receive a single-path radio frequency signal with equal amplitude and equal frequency through a single-path broadband antenna, and then send a single-path radiation signal with equal amplitude and same phase, thereby providing a single-path radiation signal with equal amplitude and same phase for a mobile terminal in an indoor space. However, due to the structural process and quality limitations of the original indoor coverage system, the coverage ranges, amplitudes and phases of the single-path transmission multi-antenna system radiation signals transmitted at the same point are inconsistent, so that the mobile terminal can only receive single-path radio frequency signals with uneven amplitudes under the coverage of signals in the same area in the moving process, the receiving effect is poor, and the MIMO application effect is poor.
