Embodiment Construction
[0027] Attached below Figure 1-7 , a specific embodiment of the present invention will be described in detail, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.
[0028] Working principle: The present invention designs a compact interdigitated magnetic metamaterial, and at the same time, integrates it between the microstrip antennas with strong interference, so that the high-order harmonics radiated from the original antenna 1 to the antenna 2 first enter the fork At this time, the LC resonance of the entire metal circuit of the interdigitated magnetic metamaterial is excited, thereby generating a negative magnetic permeability, so that the electromagnetic wave is effectively guided and suppressed, and finally the electromagnetic wave of the two antennas is realized. compatible.
[0029] In order to further understand the present invention, the present invention will be described in more detail and more ...

The invention discloses an antenna electromagnetic wave isolation device and method, and relates to the technical field of artificial electromagnetic materials and antenna decoupling. The designed isolation device is a metal loop structure arranged on a dielectric substrate, and the metal loop structure and the dielectric substrate constitute a magnetic Metamaterials, the magnetic metamaterials are used to isolate electromagnetic waves. The antenna electromagnetic wave isolation device of the present invention is compact in structure, and it is integrated into the middle of the microstrip antenna with serious electromagnetic interference to realize high-order harmonic isolation between the antennas. The structural unit of the isolation device designed in the present invention is simple and occupies The small space is also a very mature and low-cost technology in the preparation process, which is convenient for design and manufacture in large quantities.
Description
technical field [0001] The invention relates to the technical field of artificial electromagnetic material and antenna decoupling, in particular to an antenna electromagnetic wave isolation device and isolation method. Background technique [0002] New artificial electromagnetic materials, also known as electromagnetic metamaterials, have been one of the research hotspots in the scientific community in recent years. It is easy to achieve some extraordinary physical properties that are difficult to achieve with natural materials, and it can be easily manipulated by artificial design. Magnetic Metamaterials (MM for short) refers to artificial composite materials or composite structures composed of sub-wavelength unit structures with an equivalent magnetic permeability less than 1. Specifically, it can be divided into equivalent magnetic permeability less than 0 and equal to 0. and metamaterials between 0 and 1. Since the magnetic metamaterial has both a capacitive structure a...
