Embodiment Construction

[0053] The present application provides an antenna unit and an electronic device including the antenna unit. By adjusting the electrical length of the antenna unit from the feed point to the ground point, the dual mode of the slot line mode and the differential mode (D mode) of the antenna unit is realized. Covering, so that the antenna unit can generate excitation in the direction of radiation along the thickness direction of the electronic device in the slot line mode, and so that the antenna unit can generate radiation directions in the D mode respectively along the directions perpendicular to the two ends of the antenna unit excitation. Therefore, not only the antenna unit will still have good radiation performance when the electronic device is in the free space (free space, FS) state or the head-hand state (including the left-hand state and the right-hand state), avoiding the The impact of signal drop, especially the impact on low-frequency (low band, LB) signal transmiss...

Abstract

The invention provides electronic equipment. The electronic equipment comprises a radio frequency front end and an antenna unit, the antenna unit comprises an antenna body, the antenna body is provided with a feeding point and a grounding point, the antenna body comprises a first end and a second end, no gap is formed in the antenna body, the feeding point is used for being connected with the radio frequency front end, and the grounding point is used for being connected with the ground of the electronic equipment. The antenna body generates resonance of a first wavelength and resonance of a second wavelength during working, the first wavelength is larger than the second wavelength, and the electrical length of the antenna body from the feeding point to the grounding point is larger than or equal to 1 / 4 of the first wavelength and smaller than 1 / 2 of the first wavelength. Therefore, the antenna unit can maintain good radiation performance, the radiation efficiency of the antenna unit can be improved, and the antenna mode corresponding to the antenna unit can be selected based on communication requirements.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to an electronic device. Background technique [0002] With the development of full-screen electronic devices, the space for antennas is deteriorating day by day. At the same time, with the satisfaction of various user demands, the number of antennas is increasing day by day. At present, antenna units in electronic devices such as mobile phones often use conductive frames to achieve communication, that is, a plurality of gaps are opened on the conductive frame, and the sections of the conductive frame between adjacent gaps can form the antenna body of the antenna unit. . [0003] However, when holding an electronic device, it will affect the radiation of the antenna unit using the frame, resulting in a decrease in signal amplitude, which is prone to death grip and affects the radiation performance of the antenna unit. Contents of the invention [0004] This ap...
