Abstract

The embodiment of the invention discloses a radio frequency antenna device, which comprises a closed metal middle frame free of a breakpoint, a metal back cover, a transparent dielectric antenna and a liquid crystal display screen LCD, wherein the metal middle frame comprises two side frames, a top frame and a bottom frame, which are connected into a frame form; two ends of the top frame are connected to the top ends of the two side frames respectively; two ends of the bottom frame are connected to the bottom ends of the two side frames respectively; the metal middle frame is combined with the metal back cover to form a cavity; the liquid crystal display screen is arranged in the cavity; the dielectric antenna is buried into the upper surface of a glass substrate of the liquid crystal display screen; the dielectric antenna and the upper surface of the glass substrate are coplanar; a feed terminal of the dielectric antenna is electrically connected with a radio frequency circuit in the cavity; and a ground terminal of the dielectric antenna is grounded. The embodiment of the invention further discloses a mobile terminal. By the radio frequency antenna device and the mobile terminal, the antenna performance of the mobile terminal with a metal housing can be improved.

Description

technical field [0001] The invention relates to the field of antennas, in particular to a radio frequency antenna device and a mobile terminal. Background technique [0002] With the continuous improvement of users' requirements for the appearance of mobile terminals, more and more mobile terminals with metal appearance appear on the market, which leads to further deterioration of the electromagnetic environment inside the mobile terminal. The current antenna structure used by mobile terminals is: the metal middle frame is a closed structure, and the gap formed between the metal plate and the metal middle frame is used to effectively radiate electromagnetic energy. [0003] The problems of the current antenna structure are: it is necessary to design a complex feed structure to match the slot antenna; when it is necessary to adjust the resonant frequency of the slot antenna, it is realized by changing the size of the slot, and the adjustment is not flexible enough, and the ra...
