Abstract

The invention discloses a compact feeding network type artificial surface plasmon polariton (SSPP) planar antenna array, which relates to the technical field of antennas. The planar 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-to-2 power distribution network, so that the generated SSPP is not only transmitted according to the design direction, but also the SSPP energy is transmitted according to the design ratio. Using the SSPP power-dividing network to feed and decoupling through the transmission-type phase gradient metasurface, a two-way compact SSPP planar antenna array is realized. Simulation and experimental verification show that in the 6.7-14GHz frequency band, the average gain of the SSPP flat panel antenna array is 16.9dB, the total antenna efficiency is above 80%, and the highest total efficiency reaches 93.5%.

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...
