A terminal with a common radiator antenna

Abstract

The present application provides a terminal with a common radiator antenna. The terminal includes a non-grounded metal frame, a first feed source, a second feed source, a first metal body, a second metal body, a first control switch, and a second Control switch; the first signal end of the first control switch is respectively connected to the first metal body and the non-grounded metal frame, and the second signal end of the first control switch is used to connect to the first feed source of the terminal and to control the first feed source The signal connection between the first metal body and the non-ground metal frame; the first signal end of the second control switch is respectively connected to the second metal body and the non-ground metal frame, and the second signal end of the second control switch is used to connect The second feed source of the terminal is used to control the signal on-off between the second feed source and the second metal body and the non-grounded metal frame. The antenna terminal with a common radiator provided by the present application ensures the radiation efficiency of multiple antennas with a common radiator in the terminal, and realizes high isolation between multiple antennas with a common radiator.

Description

technical field [0001] The present application relates to the technical field of communication equipment, and in particular to a terminal with a common radiator antenna. Background technique [0002] An antenna is a transformer that transforms a guided wave propagating on a transmission line into an electromagnetic wave propagating in an unbounded medium (usually free space), or vice versa. Therefore, the antenna is one of the important devices to realize the communication function of communication terminals such as mobile phones. In communication terminals such as mobile phones, the antenna radiation performance is affected by its clearance area and the surrounding metal of the antenna. [0003] At present, due to the unique appearance and sense of technology of all-metal materials and high screen area, mobile phones are becoming more and more popular among consumers. However, with the development of all-metal materials and high-screen-to-occupy mobile phones, the mobile ...

Problems solved by technology

However, the signal flow of the crosstalk between the WiFi antenna and the diversity antenna is equivalent to the direct flow of part of the signal transmitted by the WiFi feed 01 and the diversity feed 02, which will cause waste of this part of the signal

And the grounding of the non-ground frame 03 makes the WiFi feed 01 and the diversity feed 02 respectively use the side part of the non-ground frame 03 as the radiator. When holding the mobile phone with both hands, the left or right hand holds the non-ground metal frame The range of the side part of 03 will reduce the radiation efficiency of WiFi antenna or diversity antenna
