Abstract

The invention discloses a compact feed network type spoof surface plasmon polariton (SSPP) panel antenna array, and relates to the technical field of antennas. The panel antenna array is composed of an SSPP power division network and a transmission type phase gradient metasurface. The SSPP power distribution network is a 1 / 2 power division network, so that the generated SSPP is transmitted according to the design direction, and the SSPP energy is transmitted according to the designed proportion. By virtue of the SSPP power division network for feeding and by virtue of the transmission type phase gradient metasurface for decoupling, the two-path compact SSPP panel antenna array is realized. Simulation and experimental verification show that the SSPP panel antenna array is 16.9dB in averagegain, 80% or above in antenna total efficiency and 93.5% in total efficiency within the frequency band of 6.7-14GHz.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a compact feeding network type artificial surface plasmon planar antenna array. Background technique [0002] A metasurface is a two-dimensional metamaterial. Different reflection / transmission "phase mutations" can be introduced through the metamaterial structural units, and these different metamaterial structural units can be spatially combined in a certain arrangement. The metasurface can realize the direction of electromagnetic wave propagation. , phase, propagation mode, polarization mode and other characteristics of free regulation. Therefore, metasurfaces can not only achieve negative reflection and negative refraction effects, but also realize novel physical properties such as polarization mode conversion, abnormal reflection / refraction effects, surface electromagnetic wave coupling and decoupling effects, and flat plate focusing. Due to the unique physical properties of...
