Abstract

Disclosed are an antenna system and a communication electronic device. The antenna system comprises a metal shell, and a WBG three-in-one antenna, a main ground metal plate and a radio frequency signal source which are arranged inside the metal shell; the metal shell comprises a first region, a second region and a slit arranged between the first region and the second region; the WBG three-in-one antenna is arranged at the bottom of the metal shell and is located in the first region; a first coupling feeding gap is arranged between the WBG three-in-one antenna and a first side wall; a second coupling feeding gap is arranged between the WBG three-in-one antenna and a second side wall; the second side wall is parallel to the slit and is located in the first region; the first side wall and the second side wall are two side walls adjacent to the metal shell; the main ground metal plate is arranged at the bottom of the metal shell and is located in a direction perpendicular to the bottom of the metal shell; and projections of the main ground metal plate and the WBG three-in-one antenna do not overlap at the bottom. According to the present application, the radiation efficiency is improved, and the consistency and reliability of signal transmission are better.

Description

technical field [0001] The present invention relates to the technical field of communication, and more specifically, relates to an antenna system and communication electronic equipment. Background technique [0002] The radio transmitter is used as a radio frequency signal source, and the output radio frequency signal 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 antenna and sent to the radio receiver through the feeder. It can be seen that the antenna is an important radio component used by communication electronic equipment to transmit and receive electromagnetic waves. Without an antenna, there is no radio communication. [0003] Since metal casings have better touch texture and strong mechanical properties, more and more electronic devices tend to use metal casings for packaging and protection. However, the metal ...
