The invention solves the low-profile and wide-band problems in the application of the existing vertically polarized antennas in the VHF section.

Description

technical field [0001] The present invention relates to the field of antennas, in particular to a miniaturized VHF (Very High Frequency) frequency band ultra-low-profile vertically polarized antenna based on a multi-chip artificial surface plasmon polariton (SSPP) 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 scenarios, the profile...

Problems solved by technology

[0004] However, the profile height of this type of antenna is generally 1 / 4 of the operating frequency wavelength, and the size is larger at low frequencies. Some vertically polarized antennas commonly used today are basically designed by using the deformation of this type of antenna. Folding is improved to inverted F antenna, inverted F antenna and other technologies to reduce the overall profile of the antenna, but its profile height can only be reduced to one tenth of the wavelength, when the profile height limit is reduced to one percent of the wavelength or below When , the traditional antenna form cannot be effective, and it is necessary to study a new ultra-low profile vertically polarized antenna
