Problems solved by technology
However, if a switch is used for selective switching, additional hardware costs must be added, and the switch circuit may aggravate the electromagnetic interference (Electromagnetic Interference, EMI) to the mobile terminal
In addition, there will be additional link loss when the signal passes through the switch circuit, which may not be able to offset the tuning compensation brought by the switch circuit

The invention discloses an antenna structure. The antenna structure comprises an antenna, a first ground feed point, a signal feed point and a second ground feed point, wherein the first ground feed point, the signal feed point and the second ground feed point are positioned on the same side of the back of a mobile terminal, and are arranged from left to right in sequence; any one of the first ground feed point and the second ground feed point serves as a reference ground feed point, and the distance between the reference ground feed point and the side on the back of the mobile terminal is smaller than a half of the back width of the mobile terminal; and the tail end of a first radiation ray contained in a low-frequency radiation unit inside the antenna does not exceed the reference groundfeed point. Moreover, the invention also discloses the mobile terminal.
Description
technical field [0001] The present invention relates to an antenna technology, in particular to an antenna structure and a mobile terminal. Background technique [0002] The RF transceiver performance of a mobile terminal such as a mobile phone is directly related to the user's call or data communication experience, and an important means to improve the RF transceiver performance is to improve the transceiver performance of the antenna. Among them, the important indicators to measure the transceiver performance of the antenna include: total radiation power (Total radiation Power, TRP) and omnidirectional receiving sensitivity (Total Isotropic Sensitivity, TIS) of free space, that is, by simulating the characteristics of free space electromagnetic field in a microwave anechoic chamber Transceiver performance of the mobile terminal obtained by testing. However, in the process of actually using the mobile terminal, the user often completes corresponding operations by holding t...
