Problems solved by technology

The common point of their research is that the model is improved based on the traditional split resonator ring, but there is no suitable model to solve the miniaturization problem of artificial metamaterial structures.
[0004] In summary, the existing literature reports have not investigated the miniaturization of artificial metamaterial structures in depth.

Embodiment Construction

[0029] The following examples describe the present invention in more detail.

[0030] In order to realize the miniaturization of the artificial metamaterial structure and establish a multi-band notch ultra-wideband antenna based on the artificial metamaterial, the present invention adopts the following steps to design a dual-band notch ultra-wideband antenna based on the artificial miniaturized metamaterial structure.

[0031] 1. Establishment of UWB antenna.

[0032] Antenna model such as Figure 1a-Figure 1b , Figure 1a-Figure 1b Denote the top and bottom views of the antenna, respectively. Areas 1 and 4 represent the copper-clad parts of the antenna, and areas 2 and 3 represent the dielectric substrate of the antenna.

[0033] For the size of the microstrip radiation patch, the first step is to select a suitable dielectric substrate.

[0034] The formula for the width w of the radiation patch is as follows:

[0035]

[0036] Among them, ε r is the dielectric constan...

Abstract

The present invention provides a dual-band trap wave ultra-wide-band antenna based on artificial miniaturized metamaterial structures. The dual-band trap wave ultra-wide-band antenna comprises an ultra-wide-band antenna. The upper half part of the front side of ultra-wide-band antenna is a copper-covering area, and the lower half part is a bare area. The middle part of the front-side copper-covering area is provided with a U-shaped bare area, the middle of the bottom side of the front-side copper-covering area is provided with a feeding line, and the bottom side of the front-side copper-covering area is arc-shaped. The lower half part of the back side of ultra-wide-band antenna is the copper-covering area, and the upper half part is the bare area. The upper side of the back-side copper-covering area is arc-shaped, and the middle of the upper side of the back-side copper-covering area is provided with a bare slot. The lower part of the ultra-wide-band antenna is provided with two artificial metamaterial structures, and the two artificial metamaterial structures are distributed at both sides of the feeding line. The front side of each artificial metamaterial structure is a square copper-covering frame, wherein the lower side of each square copper-covering frame is provided with an opening; the back side of each artificial metamaterial structure is a square bare frame, wherein theupper side of each square bare frame is provided with an opening; and each opening is provided with an inward turning section. The antenna can satisfy the trap waves under 5.15 GHz-5.35 GHz and 5.725GHz-5.825 GHz in WLAN.

Description

technical field [0001] The invention relates to a dual-band notch ultra-wideband antenna. Background technique [0002] From 1996 to 1999, J.B.Pendry and others constructed artificial metamaterials composed of thin metal rods and metal resonant rings, and verified that artificial metamaterials have the characteristics of negative permittivity (ε) and negative magnetic permeability (μ) at the same time . In 2000, R.A. Shelby and others constructed the left-handed material for the first time, making the structure of the left-handed material arouse widespread attention at home and abroad. At present, artificial metamaterials are widely used in various fields, such as microwave circuits, antenna design, etc. [0003] There are various types of combinations of artificial metamaterials based on SRR (split resonant ring) and ultra-wideband antennas, and the functions realized are also different. For example, the ultra-wideband notch antenna designed by Jaward Yaseen in 2014 was ...
