Mobile phone antenna structure supporting long term evolution (LTE) multiple input multiple output (MIMO) technology

Abstract

The invention relates to a mobile phone antenna structure supporting the LTE MIMO technology. The structure comprises a metal ground, a main antenna and a diversity antenna. The metal ground comprises a first side and a second side which are a pair of opposite sides. The main antenna is arranged on the first side of the metal ground, and the diversity antenna is arranged on the second side of the metal ground. The diversity antenna comprises a diversity antenna feeder line, a diversity antenna feeder port and a plurality of diversity antenna bending branch wires, wherein the plurality of the diversity antenna bending branch wires are connected with the metal ground respectively. One end of the diversity antenna feeder line is connected with the diversity antenna feeder port, and the other end is connected with one of the plurality of the diversity antenna bending branch wires. According to the mobile phone antenna structure supporting the LTE MIMO technology, the antenna is a high-performance LTE MIMO antenna capable of covering low frequency bands and suitable for being placed and mounted on mobile terminals of mobile phones and the like so as to solve the technical problems that good segregation and low relevance cannot be achieved simultaneously in a plurality of wide frequency bands in the prior art.

Description

technical field [0001] The invention relates to a mobile phone antenna, in particular to a mobile phone antenna structure supporting LTE MIMO technology. Background technique [0002] As a next-generation wireless communication technology, LTE (Long Term Evolution, a next-generation wireless communication standard) can provide faster data rates and better multimedia services. In LTE technology, MIMO (Multiple Input Multiple Output, referring to the use of multiple transmit antennas at the transmitter and multiple receive antennas at the receiver) is the most critical technology. To achieve MIMO operation, two or more receive and transmit antennas operating at the same frequency are required. Several main indicators to measure the quality of MIMO antennas include: radiation efficiency, isolation, and correlation coefficient. These indicators will have a crucial impact on the performance of the entire system. However, since mobile terminals such as mobile phones are general...
