Horizontally Polarized Omnidirectional Antenna Based on Artificial Localized Surface Plasmons

A technology of localized surface plasmon and artificial surface plasmon, which is applied in the direction of antenna, antenna grounding switch structure connection, and devices that make the antenna work in different frequency bands at the same time. Due to the large size of the antenna and the large fluctuation of the gain of the slotted antenna, the effects of simple production, convenient processing and simple adjustment are achieved.

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...
