Abstract

The invention provides a frequency adjustable band-pass frequency selective surface structure. The frequency adjustable band-pass frequency selective surface structure comprises a dielectric plate anda metal patch and a graphene patch which are arranged on the upper surface of the dielectric plate, wherein an annular slot is formed in the metal patch, the annular slot is internally provided withthe graphene patch in the shape of an annular ring, and the graphene patch is seamlessly laminated inside the annular slot; and a cross-shaped slot is formed in the middle of a circular area surrounded by the graphene patch. According to the frequency adjustable band-pass frequency selective surface structure provided by the invention, the frequency adjustable function under different frequenciescan be realized.

Description

technical field

[0001] The invention relates to the field of communication technology, in particular to a frequency-adjustable band-pass frequency selection surface structure. Background technique

[0002] A frequency selective surface (FSS) is a single-screen or multi-screen periodic array structure composed of a large number of passive resonant units, which is composed of periodically arranged metal patch units or periodically arranged aperture units on a metal screen. This surface can be totally reflective (patch type) or fully transmissive (aperture type) near the cell's resonant frequency. It is often referred to as a "spatial filter" by people in the industry.

[0003] However, the existing passive frequency selective surface structure cannot realize the function of frequency tunability in different frequency bands, and cannot meet the multi-band / broadband requirements in existing communication systems. Contents of the invention

[0004] The purpose of the present ...
