Antenna radio frequency optimization method and device and mobile terminal

Abstract

The embodiment of the invention discloses an antenna radio frequency optimization method and device and a mobile terminal. The method comprises the following steps: acquiring at least two radio frequency modules with the same frequency band configuration; judging the splitting frequency according to the transmitting frequency of the configuration frequency band of the radio frequency modules; andobtaining updated frequency band configuration corresponding to the radio frequency modules according to the splitting frequency. According to the scheme, under the condition that the product requirement is not changed, a radio frequency signal path is redistributed and a radio frequency path is multiplexed, so that the radio frequency cost is reduced, the purpose of reducing the antenna difficulty is achieved, and the overall performance of the antenna radio frequency is improved.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an antenna radio frequency optimization method, device and mobile terminal. Background technique [0002] At present, all 5G mobile phones on the market support ENDC (EUTRA-NR Dual Connectivity), that is, dual connection between LTE and 5G NR frequency bands. The ENDC combinations that Sub6G usually needs to support include: L+L, L+M, L+H, L+ Combinations of UH, M+M, M+H, M+UH, and H+UH (the abbreviations will be explained in detail below). At the same time, M, H, and UH frequency bands will all require support for downlink 4x4 MIMO, so the antenna of the entire mobile phone will have at least two low-frequency main antennas with transmission, two intermediate-frequency main antennas with transmission, and 1 to 2 low-frequency antennas that only receive. 2 receive-only IF antennas. If 5G NR SA (Standalone) mode is supported, n41 and n78 will require support for uplink MIMO, then there w...

Problems solved by technology

At this time, the mobile phone has more and more antennas and more and more frequency bands, which makes the performance of the antennas on each frequency band dwarf, and often the performance of many frequency bands is not ideal.

[0003] At the same time, the current mainstream full-screen design and the addition of millimeter-wave antennas have resulted in less and less space for Sub6G antennas. 5G mobile phones have generally added GPS L5 and WiFi MIMO functions. All functional frequency bands have further increased. Even with tuning technology and Antenna combination technology, the performance of some frequency bands is still difficult to achieve better
