Problems solved by technology

In addition, due to the high dielectric constant of the non-metallic battery cover, it is also easy for the millimeter wave to generate surface waves on the battery cover, thereby reducing the performance of the millimeter wave antenna

Abstract

The invention discloses an electronic device which comprises a middle frame, wherein the middle frame comprises a middle plate and an annular frame, the outer circumferential wall of the middle plateis connected with the inner circumferential wall of the annular frame, a mounting groove is defined by the middle plate and the annular frame, and a through hole penetrating through the annular framein the thickness direction of the annular frame is formed in the annular frame; a waveguide antenna which is arranged in the through hole; a circuit board which is arranged in the mounting groove, wherein a radio frequency integrated circuit is arranged on the circuit board; a feed line, wherein one end of the feed line is connected with the radio frequency integrated circuit, the other end of thefeed line is connected with the waveguide antenna, and the radio frequency integrated circuit feeds an excitation signal to the waveguide antenna through the feed line so as to excite the waveguide antenna to transmit and / or receive an electromagnetic wave signal from the through hole. According to the electronic device, the internal space of the electronic device can be saved, and the influenceof functional devices in the electronic device on the radiation performance of the waveguide antenna can be reduced.

Description

technical field [0001] The present application relates to the technical field of electronic devices, in particular to an electronic device. Background technique [0002] In related technologies, the millimeter wave module (antenna + IC) is built into the frame of the mobile phone, and the transmission and reception of the millimeter wave is completed by opening an antenna window on the frame or using a non-metallic battery cover. However, with the development of mobile phones in the direction of thinner, lighter and multi-functional, the internal environment of mobile phones is becoming more and more complex. Functional devices such as cameras, earpieces, and MICs will all reduce the radiation performance of the antenna. At the same time, because the wavelength of the millimeter wave is very short, it is more sensitive to the impact of the environment. In addition, due to the high dielectric constant of the non-metallic battery cover, it is also easy for the millimeter wave...
