Abstract

The invention discloses a multi-layer dual-frequency broadband antenna and communication equipment, comprising: a dielectric substrate, a first radiating patch, a second radiating patch, a feeding part, and a signal input piece; the feeding part includes a feeding probe, a gradient The transmission line, the two ends of the feeding probe are respectively electrically connected to the first radiation patch and the tapered transmission line, and the other end of the tapered transmission line is electrically connected to the signal input chip; wherein, both the first radiation patch and the second radiation patch have two symmetrical axis, the length of the first radiating patch along one of its symmetry axes is greater than that along its other symmetry axis, the length of the second radiating patch along its one symmetry axis is greater than its length along its other symmetry axis, and the length of the first radiating patch along its other symmetry axis, along the dielectric substrate The surface normal direction of the first radiation patch overlaps with the second radiation patch, and the first radiation patch is smaller than the second radiation patch; the feeding position of the feeding probe electrically connected to the first radiation patch deviates from the first radiation patch The two symmetry axes of the patch are set. The invention has the technical characteristics of ultra-low profile, dual-frequency broadband and simple structure.

Description

technical field [0001] The invention belongs to the technical field of mobile communication, and in particular relates to a multi-layer dual-frequency broadband antenna and communication equipment. Background technique [0002] In the context of the rapid development of the Internet of Everything, the acquisition and application of information are becoming more and more important, and the acquisition of information requires information transmission based on antennas. With the development of communication technology, mobile communication devices such as mobile phones and notebook computers have more and more functions, and the number of antennas also increases with the enrichment of functions, but the internal space is also more and more tight. [0003] In the existing antenna technology, the method of realizing dual frequency mainly includes two feeds exciting two different radiating elements at the same time, namely double-fed dual element, or two feeds excite two radiating...
