Background technique

Antenna performance of mobile communication terminals (especially mobile phones) In addition to the use of free space, handheld scenes often appear. In a handheld application scenario, there is a situation in which a person touches or is placed near an antenna. At this time, some measures need to be taken to avoid or reduce the influence of the addition of a human hand on the performance of the antenna. The technical solutions for solving the influence of the human hand on the antenna include: debugging the antenna, changing the grounding of the antenna, adjusting the matching form of the antenna, adding the tuned antenna switch, adopting the multi-antenna form, and the like.

However, the size of the mobile communication terminal, the layout of the main board, the layout of the components, the shape, etc. may be different, which may make the design of the antenna of the mobile communication terminal more difficult. In special cases, the mobile communication terminal is not even suitable for the above technical solution. The application scenario, if the application scenario of the technical solution is not suitable, may result in insufficient communication performance of the mobile phone, and those skilled in the art can only improve the mobile communication terminal to enable the mobile communication terminal to satisfy at least one of the above technical solutions to solve the mobile communication. The antenna of the terminal avoids the human hand problem.
