Problems solved by technology

[0003] The most common way to achieve dual-band is to use shared aperture technology to put resonators of different frequencies together. The problem is that this requires additional consideration of the impact of coupling between different resonant parts on the performance of the unit, which not only greatly increases the antenna The size of the unit increases the design complexity and increases the production cost. Therefore, it is necessary to design a dual-band circularly polarized transmission antenna

Abstract

The invention discloses a dual-band transmission type antenna. The dual-band transmission type antenna comprises a dielectric substrate and metal panels. The dielectric substrate is a square plate, the metal panels are circular plates, there are several metal panels and the metal panels are arranged in rows and columns and attached to a front surface and a back surface of the dielectric substrate.Each metal panel is a pattern generated after etching and hollowing, and the pattern is divided into an internal resonance structure, an external resonance structure and a middle isolation circular ring with a circle center as a benchmark. In the invention, each metal panel is used as a basic unit; the plurality of metal panels are arranged in rows and columns and attached to the front surface and the back surface of a dielectric substrate to form the dual-band transmission type antenna. Compared with a traditional single-band transmission type antenna, the dual-band transmission type antennahas advantages that the resonance structure is shaped, independent regulation and control performance on different frequency bands and a dual-band working characteristic are particularly outstanding,the structure is simple, transmission efficiency is high, and manufacturing is convenient.

Description

technical field [0001] The invention relates to the technical fields of microwave, wireless communication and test simulation, in particular to a dual-band transmission antenna. Background technique [0002] Metamaterials refer to some composite materials with artificially designed structures and exhibit extraordinary physical properties that natural materials do not have. Since the concept of metamaterials was put forward, the technology has become more and more mature. Metamaterial units working in the microwave frequency band have the characteristics of small size, light weight, low profile, and easy integration. The transmissive metamaterial antenna element is a kind of phase shifter, which has a small profile, low quality, and planar characteristics, and is widely used in wireless communication systems. As spectrum resources become increasingly tight, and in order to reduce mutual interference between antennas operating in different frequency bands, the dual-frequency ...
