Abstract

The invention provides a low-profile vertically polarized end-fire antenna based on an artificial surface plasmon structure, including: 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 evenly distributed above the floor; the top SSPPs loading structure is directly connected to the SSPPs transmission and radiation structure; the top SSPPs loading structure is parallel to the floor plane; The left side of the antenna; the SMA connector feeds the SSPPs antenna. The invention can effectively reduce the working wavelength of the antenna by combining the wavelength shortening effect of the SSPPs theory, thereby realizing the purpose of miniaturization.

Description

Low-profile vertically polarized endfire antenna based on artificial surface plasmon structure technical field The present invention relates to the technical field of antennas, in particular, to a kind of ultra-low Cross-section vertically polarized end-fire antennas, in particular to a multi-band structure based on artificial surface plasmon polaritons (SSPPs for short) Low profile vertically polarized endfire antennas, and can form nearly omnidirectional radiating arrays. Background technique The continuous progress of science and technology and the ever-increasing demands of all aspects of society have promoted the rapid development of wireless communication technology.
