Problems solved by technology

[0003] However, the working bandwidth of the traditional microstrip antenna is relatively narrow, and the usual methods to increase the bandwidth include irregular metal patches, opening slits on the metal patches, etc. These two methods can increase the bandwidth of the antenna is limited, and it is easy to use The radiation pattern of the antenna is distorted; in addition, in order to ensure the antenna index, the size of the traditional microstrip antenna must be half of its working wavelength, resulting in a larger shape and unable to meet the miniaturization requirements

Embodiment Construction

[0031] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0032] Microstrip antennas have the advantages of low profile, light weight, and easy processing. However, due to its radiation principle, the general working bandwidth is narrow. How to increase the bandwidth of the microstrip antenna and reduce the size of the microstrip antenna without affecting the radiation of the microstrip antenna is the focus and difficulty of our research.

[0033] In one embodiment, refer to figure 1 as well as figure 2 , provides a microstrip antenna, including a first dielectric substrate 100 , a second dielectric substrate 200 , a first ra...

Abstract

The invention relates to a dual-polarized mesh antenna, which comprises a first dielectric substrate; a second dielectric substrate disposed at a distance from the first dielectric substrate; a firstmesh-shaped radiation patch disposed on the surface, close to the second dielectric substrate, of the first dielectric substrate and used for radiating and generating a first resonance peak; a secondmesh-shaped radiation patch disposed on the surface, away from the first dielectric substrate, of the second dielectric substrate and used for radiating and generating a second resonance peak; and a reflective ground metal plate disposed on one side of the first radiation patch and the second radiation patch, wherein a difference between a wavelength corresponding to the first resonance peak and awavelength corresponding to the second resonance peak is within a preset range. The dual-polarized mesh antenna disclosed by the invention can effectively expand the frequency bandwidth and reduce the antenna size.

Description

technical field [0001] The present application relates to the technical field of communications, in particular to a dual-polarized grid antenna. Background technique [0002] With the development of communication technology, microstrip antenna technology has emerged, and its market demand is increasing. In particular, the miniaturization characteristics of the current 5G antenna technology are more dependent on the microstrip antenna structure. The microstrip antenna (microstrip antenna) is usually on a thin dielectric substrate, one side is attached with a conductive thin layer (usually a metal thin layer) as a reflective grounding metal plate, and the other side is made into a radiation patch of a certain shape, and the radiation patch chip-fed antenna. Microstrip antennas have the advantages of low profile, light weight, and easy processing. [0003] However, the working bandwidth of the traditional microstrip antenna is relatively narrow, and the usual methods to incre...
