Abstract

The invention provides a low-profile vertical polarization antenna unit design based on an artificial surface plasmon structure and an omnidirectional array structure after array formation. The antenna comprises a microstrip line excitation structure, an SSPPs patch transmission and radiation structure arranged in a single-side comb shape, a dielectric layer and an SMA connector. The SMA connectoris used for carrying out feed excitation on the antenna; and the SSPPs transmission and radiation structure in the single-side comb shape adopts a microstrip line for coupling feed. According to theinvention, the problem of high profile of the existing low-frequency vertical polarization omnidirectional antenna is solved, 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. 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. [0003] Usually, end-fire antennas are implemented by Vivaldi antennas, horn antennas, etc., but the profile height of such antennas is generally 1 / 2 the wavelength of th...
