Embodiment Construction

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0029] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, the ...

Abstract

The invention discloses a double-frequency omnidirectional antenna. The double-frequency omnidirectional antenna comprises a first patch, a first dielectric substrate, a second patch, a second dielectric substrate, and a grounding plate which are orderly laminated, and a metal probe connected with a feed port after orderly penetrating the first dielectric substrate, the second patch, the second dielectric substrate and the grounding plate; the clearance is retained between the metal probe and the second patch, and one end, far away from the feed port, of the metal probe is propped against thefirst patch, thereby enabling the metal probe to directly feeding on the first patch and performing the coupling feeding on the second patch, wherein the sizes of the first patch and the second patchare different. The double-frequency omnidirectional antenna has wide impedance width and axial ratio bandwidth, and has good omnidirectional radiation feature; the omnidirectional antenna disclosed bythe invention is simple in structure, low in section and especially suitable for the current wireless communication system.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a dual-frequency omnidirectional antenna. Background technique [0002] With the rapid development of wireless communication technology, the role of antennas in communication systems is becoming more and more important. In recent years, dual-band antennas have received extensive attention. Compared with traditional single-frequency antennas, dual-frequency antennas can cover more communication frequency bands, thereby reducing costs. In the prior art, the bandwidth of the dual-frequency antenna is very narrow, and the structure is relatively complicated at the same time, which cannot meet the requirements of today's wireless communication system. Contents of the invention [0003] The main purpose of the present invention is to provide a dual-frequency omnidirectional antenna, aiming at solving the problems of narrow bandwidth and complicated structure of the dual-frequ...
