Problems solved by technology

[0004] In recent years, with the continuous development of wireless communication technology, the functions of communication electronic equipment have become more and more powerful, such as smart phones, smart watches, etc., and the integration has become higher and higher, resulting in smaller and smaller volumes of communication electronic equipment. The space of the antenna device is getting smaller and smaller, resulting in a gradual decrease in the radiation efficiency of the antenna device

Abstract

The invention discloses a communication electric device and an antenna device. The antenna device includes an antenna unit used for transceiving wireless signals; and a first metal component and a second metal component arranged oppositely, wherein a radiation gap is arranged between the first metal component and the second metal component; and feed points of the antenna unit are arranged in the gap. The antenna device adopts the radiation gap between the first metal component and the second metal component as a radiation body of the antenna, so that the radiation efficiency of the antenna device is improved. The first metal component and the second metal component can be metal structures of the communication electric device and no external component structures are needed to add. Therefore, the radiation efficiency of the antenna device is improved without increasing space occupancy.

Description

technical field [0001] The present invention relates to the technical field of communication, more specifically, to a communication electronic device and an antenna device thereof. Background technique [0002] This section is intended to provide a background or context to the implementations of the application that are recited in the claims. The descriptions herein may include concepts that could be explored, but not necessarily concepts that have been previously thought of or explored. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. [0003] The radio frequency signal power output by the radio transmitter is sent to the antenna through the feeder, and is radiated by the antenna device in the form of electromagnetic waves. After the electromagnetic wave reaches the receiving location, it is followed by the ant...
