Embodiment Construction

[0024] In order to make the technical solutions, features and advantages of the present invention clearer, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0025] figure 1 It is the top view of loading the left-handed material on the rectangular patch microstrip antenna of the present invention.

[0026] Such as figure 1 The top view of the rectangular patch microstrip antenna loaded with left-handed material can be clearly seen as shown. Different from other antennas, this structure does not need to coat metal wires on the back of the dielectric layer, which is more convenient and simple to design.

[0027] figure 2 It is a schematic diagram of a double-opened triangular resonant ring model of the present invention.

[0028] Such as figure 2 The new left-handed material structural unit shown is composed of two upper and lower open triangular resonant rings and a closed loop in the middle, so...

Abstract

The invention discloses a novel left-handed material used for a rectangular microstrip patch antenna. According to a method, dual-opening triangular resonant ring metal patterns are etched on one side of a dielectric substrate by adopting a circuit board, so that each of a dielectric constant and magnetic permeability is a negative value. An S parameter diagram of the structure is analyzed, so that the dual-negative structure of the novel left-handed material really exists. The antenna comprises a radiation element, a left-handed material layer, a dielectric layer and a reference ground, wherein the left-handed material layer is simple in structure and convenient to use. The conventional rectangular microstrip patch antenna has the shortcomings of narrow working band, low gain, low end-fire performance, low power capacity and the like. The advantages of the novel left-handed material are taken into account, and the novel left-handed material is loaded to the rectangular microstrip patch antenna, so that the related characteristics of the conventional antenna system can be improved to a certain extent.

Description

technical field [0001] The invention relates to the field of application of left-handed materials to antennas, in particular to a research system on a rectangular patch microstrip antenna loaded with a left-handed material layer. Background technique [0002] Left-handed materials are a class of materials that have both negative magnetic permeability and negative permittivity in a certain frequency band. Left-handed materials have some unique electromagnetic properties. Such as inverse Doppler effect, inverse Chelokov radiation and super lens, etc., have important application value. Left-handed materials can be used in the research of highly directional antennas, electromagnetic wave stealth, couplers, etc. With the continuous development of science and technology, left-handed materials will be widely used in wireless communication systems. Most left-handed materials are a combination of resonant rings and thin wires. Although some people have proposed different shapes o...
