Embodiment Construction

[0037] figure 1 The antenna structure of the prior art shown includes a feeder 2 and an artificial metal microstructure 1, wherein the topological patterns of the artificial metal microstructure 1 are varied, as Figure 1a to Figure 1e shown. All the patterns in the figure are planar patterns and take up a lot of space, so they can all be improved by utilizing the design ideas of the present invention. One of the patterns is selected for detailed description below, but it should be known that the design of other patterns can be easily obtained by utilizing the principle of the present invention.

[0038] At the same time, in order to adapt to the shape of the planar space reserved for the antenna inside the electronic device, the cross-sectional shape of the multilayer substrate of the present invention can be designed in various shapes, such as circular, elliptical, polygonal, etc. The embodiments described below all use a quadrilateral substrate as an example for illustrat...

Abstract

The invention relates to a metamaterial radio frequency antenna with multiple layers of substrates and a making method thereof. The metamaterial radio frequency antenna with multiple layers of substrates comprises a plurality of substrates stacked together, metal branches are respectively attached to the substrates, and the metal branches above adjacent substrates are electrically connected. In the invention, the planar metal microstructure and feeders of the traditional metamaterial radio frequency antenna become three-dimensional and spatial, the space occupied by the antenna is utilized to maximum extent, and the antenna is further miniaturized.

Description

technical field [0001] The invention relates to an antenna and a preparation method thereof, in particular to a metamaterial radio frequency antenna with a multi-layer substrate and a preparation method thereof. Background technique [0002] The antennas in existing communication systems are mainly dipole antennas and PIFA antennas. The important indicators such as the size, bandwidth, and gain of such antennas are limited by basic physical principles (gain limit, bandwidth limit, etc. under a fixed size). The basic physical principles of these index limits make the miniaturization of antennas far more difficult than other devices, and due to the complexity of electromagnetic field analysis of radio frequency devices, approaching these limit values ​​has become a huge technical challenge. Therefore, when the design encounters the problems of small space, low operating frequency, and multi-mode operation of the antenna, it seems powerless. [0003] In order to solve the abov...
