Embodiment Construction

[0018] The present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0019] Metamaterials (artificial electromagnetic materials) refer to topological metal microstructures carved from metal sheets into specific shapes, and the topological metal microstructures of specific shapes are placed on a substrate with a certain dielectric constant and magnetic permeability. Equivalent to special electromagnetic materials, its performance parameters mainly depend on its subwavelength specific shape topological metal microstructure. In the resonant frequency band, artificial electromagnetic materials usually exhibit high dispersion characteristics. In other words, the impedance, capacitive inductance, equivalent permittivity and magnetic permeability of the antenna will change drastically with frequency. Therefore, artificial electromagnetic material technology can be used to modify the basic characteristics of the antenna, so t...

Abstract

The invention relates to an outdoor unit based on a metamaterial antenna. The outdoor unit based on the metamaterial antenna comprises a baseband signal processing unit, an uplink, a lower link, a duplexer and an antenna. The antenna is the metamaterial antenna which comprises an antenna body and a metamaterial panel which is arranged on one side of the antenna body. The metamaterial panel is divided into a plurality of layers. Each layer is composed of a slice-shaped base and a plurality of artificial metal microstructures which are arranged on the base. Due to the fact that the existing antenna is replaced by the metamaterial antenna and the metamaterial panel is arranged on one side of the antenna body, most electromagnetic waves produced by radiation vibrators are reflected by the metamaterial panel and are converged in the same direction, therefore the width of a radiation wave lobe is greatly reduced, the gain of a radio frequency antenna is obviously improved, signal strength of radio frequency antenna is greatly increased, and the metamaterial antenna is capable of being used in various severe environments, small in size and low in cost.

Description

technical field [0001] The present invention relates to a communication device, in particular to an outdoor unit based on a metamaterial antenna. Background technique [0002] Microwave communication technology refers to the transmission of data between microwave devices directly through space in the form of microwaves, without laying optical fibers or cables, etc. It has obvious engineering advantages in cities, remote areas or special areas (such as rivers, etc.). Microwave technology is convenient for networking, flexible in use, and short in service provisioning time. With the development of microwave technology, the cost of microwave equipment is gradually reduced, so the use of microwave technology is becoming more and more extensive. Indoor Unit (IDU) and Outdoor Unit (Outdoor Unit, ODU) are two common microwave devices. The IDU is connected to the ODU through an intermediate frequency cable. The IDU controls the ODU through the intermediate frequency cable. The ODU ...
