Abstract

The invention provides a vertical polarization omni-directional antenna based on a spoof surface plasmon polariton structure. The vertical polarization omni-directional antenna comprises a monopole excitation structure (1), single-sided / double-sided sawtooth-shaped SSPPs transmission radiation structures (2), a limited floor (3), and an SMA connector, wherein the SMA connector is used for carryingout radio frequency excitation on a monopole antenna, namely the monopole excitation structure (1); feeding of a plurality of single-sided / double-sided sawtooth-shaped SSPPs transmission radiation structures, namely the transmission radiation structures (2), is subjected to coupling feeding through the monopole antenna; and the single-sided / double-sided sawtooth-shaped SSPPs transmission radiation structures are arranged on a dielectric plate structure of the antenna. The vertical polarization omni-directional antenna solves the problem of directional diagram offset caused by low frequency band, high profile and limited ground of an existing vertical polarization omni-directional antenna.

Description

technical field [0001] The present invention relates, in particular, to a vertically polarized omnidirectional antenna based on an artificial surface plasmon structure, and in particular to a low-profile vertically polarized omnidirectional antenna based on an artificial surface plasmon structure. 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 of the antenna, the miniaturization and low profile of the antenna is an inevitable trend of development. At the same time, in some specific application...
