ANTENNA OF MOBILE TERMINAL AND MOBILE TERMINAL

WIPO Patent Application WO/2019/090690

A1

An antenna of a mobile terminal and the mobile terminal. The antenna comprises a radiator, the radiator comprising a first portion, a second portion, and a third portion which are separated by gaps; the end of the second portion close to the first portion is a first end, and the end of the second portion close to the third portion is a second end; a medium-high-frequency feeder line is electrically connected to the radiator at a first connection point; a low-frequency feeder line is electrically connected to the radiator; a first grounding wire is electrically connected to the radiator at a second connection point, and the first grounding wire is provided with an adjustable device for controlling on-off of the first grounding wire; the length of one of the first end and the second end more distant from the first connection point to the second connection point is a quarter of a wavelength corresponding to required resonance frequency. By controlling on-off of the first grounding wire, the antenna utilizes a low-frequency radiator to excite a new medium-high-frequency resonance, so as to increase the bandwidth of the medium-high frequency.
