Abstract

The invention discloses a non-reflective back board and large-caliber spoof surface plasmon polariton (Spoof Surface Plasmon Polariton, SSPP) wide-band frequency sweep planar antenna, and relates to the technical field of an antenna. The planar antenna consists of a non-reflective back board waveguide structure and a wide-band transmission type phase gradient metasurface; a long-range propagated SSPP can be generated on the non-reflective back board SSPP waveguide structure, so that the longitudinal antenna caliber of the SSPP planar antenna can be expanded; by virtue of planar antenna arraying, the transverse antenna caliber of the planar antenna can be further expanded; on the basis, the SSPP planar antenna with the antenna caliber of 300mm*30mm and a large-caliber high-directivity SSPPplanar antenna array with the antenna caliber of 300mm*240mm are designed; a simulation and experimental result proves that the gain of the antenna array is improved by 9.2dB on average compared withthe single SSPP antenna while the working bandwidth and the frequency sweep characteristic are basically the same as those of the single antenna; and by virtue of the non-reflective back board SSPP planar antenna designed on the basis, the invisible design of the planar antenna can be facilitated, and design of a conformal antenna can be promoted.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a non-reflection backboard and a large-diameter artificial surface plasmon broadband frequency-scan flat panel antenna. Background technique [0002] Metasurface is a two-dimensional metamaterial, which can realize the free regulation of parameters such as electromagnetic wave amplitude, phase, polarization, and wave vector. Novel physical properties such as artificial surface plasmon polaritons (Spoof Surface Plasmon Polariton, SSPP) coupling and decoupling, and polarization mode conversion can be realized. With their unique physical properties, excellent electromagnetic control ability, flexible design methods and subwavelength structural properties, metasurfaces have broad application prospects in the field of antennas. [0003] Free space propagating waves can be coupled into SSPP, and according to the principle of reversibility of electromagnetic waves, SSPP can also be co...
