Abstract

The invention discloses an electronic device, and belongs to the technical field of antennas. The electronic device comprises a metal middle frame, a sound cavity shell, a sound cavity metal body, a sound cavity metal supporting sheet and a feed source. The sound cavity shell is fixed on the metal middle frame, the sound cavity metal body and the sound cavity metal supporting sheet are arranged inan inner cavity of the sound cavity shell at intervals, and the sound cavity metal body and the metal middle frame are arranged in an insulating manner. The feed source is used for feeding an excitation signal into the sound cavity metal body to excite the sound cavity metal body to resonate at a first resonant frequency, and the excitation signal is also coupled to the sound cavity metal supportsheet through a gap between the sound cavity metal body and the sound cavity metal support sheet to excite the sound cavity metal support sheet to resonate at the first resonant frequency. Accordingto the application, when the feed source feeds the excitation signal to the sound cavity metal body, the electronic device can be in the working mode of a microstrip antenna with the 1 / 2 working wavelength, so that the high-efficiency radiation and directionality of the electronic device are ensured.

Description

technical field [0001] The present application relates to the technical field of antennas, in particular to an electronic device. Background technique [0002] At present, during the use of electronic equipment, in order to ensure the performance of the antenna of the electronic equipment, antenna devices are fixedly installed. In order to ensure the rationality of the installation of the antenna device, the metal frame of the electronic device is used as the radiator to set the antenna device. For example, the metal frame can be used as a radiator by a design scheme of slits on the bottom or both sides of the metal frame. However, by using the metal frame as a radiator, the radiation efficiency is low, and the radiation pattern is nearly omnidirectional, thereby degrading the antenna performance of the electronic device. Contents of the invention [0003] The present application provides an electronic device, which can realize the directivity of the beam radiation direc...
