Abstract

The invention provides a low-profile vertically polarized antenna unit design based on an artificial surface plasmon structure and an omnidirectional array structure after formation; including a microstrip line excitation structure and a single-sided comb-like arrangement of SSPPs patch transmission With the radiation structure, the dielectric layer, and the SMA connector; the SMA connector is used to feed and excite the antenna; the SSPPs arranged in a single-sided comb-like transmission and the radiation structure feed adopt a microstrip line for coupling feed. The invention solves the problem of high profile of the existing low-frequency vertically polarized omnidirectional antenna, and the antenna can realize beam scanning.

Description

technical field [0001] The present invention relates to an antenna, in particular to a low profile vertically polarized omnidirectional / beam scanning antenna based on SSPPs. 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. As an important part of wireless communication systems, antennas have gradually received more attention. On various carriers such as satellites, automobiles, ships, etc., 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 are an inevitable trend of development. [0003] Usually, end-fire antennas are realized by Vivaldi antennas, horn antennas, etc., but the section height of such antennas is generally 1 / 2 the wavelength of the...
