Abstract

The invention relates to the technical field of communication, particularly to a multi-frequency antenna and communication equipment comprising the same. The multi-frequency antenna comprises a dielectric substrate, wherein a grounding plate is arranged on the surface of one side of the dielectric substrate, a high-frequency radiation unit and a low-frequency radiation unit are arranged on the surface of the other side of the dielectric substrate, the high-frequency radiation unit comprises a circular first resonance body and a plurality of rectangular grooves formed in the first resonance body, and the low-frequency radiation unit comprises disturbance branches connected to the edge of the first resonance body and a conductor used for connecting the two disturbance branches. According tothe multi-frequency antenna, the impedance of the antenna can be adjusted by forming the rectangular groove in the circular first resonance body so as to form the high-frequency part of the antenna, and the disturbance branches are connected together by using the conductor structure so as to form the low-frequency part of the antenna, so that the coverage of multiple frequency bands is realized, and the overall structure of the product is flat-plate-shaped so as to achieve the small occupied space.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a multi-frequency antenna and a communication device including the same. Background technique [0002] In wireless communication applications, because of the needs of some communication standards or because the communication equipment integrates multiple communication systems, etc., the communication equipment often needs to work in multiple frequency bands at the same time, so the communication equipment needs to work in multiple frequency bands antenna system, or an antenna system that can work in multiple frequency bands. In terms of corresponding antennas, existing wireless communication devices often have to build multiple antennas (such as WiFi antennas, GPS antennas, etc.) to support various communication functions respectively. [0003] In the process of implementing the present application, the inventors found that the related technology has at least the following...
