Abstract

The invention relates to a horizontally polarized omnidirectional antenna based on artificial local area surface plasmon. The antenna mainly comprises a dielectric plate, an artificial surface plasmonwaveguide structure and a coplanar waveguide matching structure which are located on the back surface of the dielectric plate, and an artificial local surface plasmon resonance unit structure on thefront surface of the dielectric plate. According to the invention, omnidirectional radiation horizontally polarized electromagnetic waves can be obtained. The antenna is manufactured by adopting a common PCB process, is convenient to process, has the characteristics of miniaturization and low profile, improves the integration level of a system, and has a good application prospect.

Description

technical field [0001] The invention belongs to the field of artificial electromagnetic materials and relates to a horizontally polarized omnidirectional antenna based on artificial localized surface plasmons. Background technique [0002] Antenna is an indispensable part of wireless communication, and its basic function is to transmit and receive radio waves. An omnidirectional antenna refers to a 360° uniform radiation on the horizontal plane and a beam with a certain width on the vertical plane. Omnidirectional antennas are generally used in mobile communication systems to cover large areas with low-density users. With the continuous improvement of society's requirements for communication systems, the demand for omnidirectional antennas is gradually increasing. [0003] Through the design of artificial electromagnetic materials, surface waves similar to surface plasmons can be realized in low-frequency (such as microwave, terahertz, and far-infrared) bands. Such surface...
