Abstract

The invention provides a low-profile vertically polarized end-fire antenna based on an artificial surface plasmon structure. The antenna comprises a microstrip line excitation structure, an SSPPs transmission and radiation structure, a top SSPPs loading structure, a dielectric layer and an SMA connector; the SSPPs transmission and radiation structure is uniformly distributed above a ground plate;the top SSPPs loading structure is directly connected with the SSPPs transmission and radiation structure; the top SSPPs loading structure is parallel to the plane of the ground plate; the SMA connector is located on the left side of SSPPs antennas arranged in a unilateral comb shape; the SMA connector is used for feeding the SSPPs antennas. By combining the wavelength shortening effect of the SSPPs theory, the working wavelength of the antenna can be effectively reduced, so that the purpose of miniaturization is achieved.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an ultra-low-profile vertically polarized end-fire antenna based on an artificial surface plasmon structure, and in particular to a multi-layer antenna based on an artificial surface plasmon (SSPPs for short) structure. Frequency band low-profile vertically polarized end-fire antenna, and can form an array with near omnidirectional radiation. Background technique [0002] The continuous progress of science and technology and the increasing demands of all aspects of society have promoted the rapid development of wireless communication technology. Antennas, as an important part of wireless communication systems, have gradually received more attention. On various carriers such as satellites, automobiles, and ships, communication equipment is also indispensable, and the requirements for antennas are becoming more and more stringent. On the basis of ensuring the performance ...
