Abstract

The application discloses an electronic device, comprising: a middle frame, the middle frame includes a middle plate and an annular frame, the outer peripheral wall of the middle plate is connected with the inner peripheral wall of the annular frame, the middle plate and the annular frame define a mounting groove, and the annular frame is provided with There is a through hole running through it in its thickness direction; waveguide antenna, waveguide antenna is set in the through hole; circuit board, the circuit board is set in the installation groove, and the circuit board is equipped with radio frequency integrated circuit; feeder line, feeder line One end of the feeder is connected to the radio frequency integrated circuit, and the other end of the feeding line is connected to the waveguide antenna. The radio frequency integrated circuit feeds an excitation signal to the waveguide antenna through the feeder line to excite the waveguide antenna to transmit and / or receive electromagnetic wave signals from the through hole. According to the electronic device of the present application, not only the space inside the electronic device can be saved, but also the influence of functional devices inside 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...
