Abstract

The invention provides a frequency selection surface structure based on a stereo structure, relates to the frequency selection surface structure and solves the problems that an existing frequency selection surface of a simple structure has fewer controllable parameters and is small in gradient of a frequency response curve, poor in polarization stability and poor in miniaturization in practical application. According to the invention, four No.1 medium plates are perpendicularly spliced to form a rectangular frame, a metal film layer is coated on the inner side wall of the rectangular frame, circular through holes are formed in the No.1 medium plates, and the a metal film layer is coated on the inner side of each circular through hole; and two No.2 medium plates are respectively arranged in the rectangular frame, one pair of opposite edges of each No.2 medium plate is fixedly connected with the inner side wall of the rectangular frame, the two No.2 medium plates are perpendicularly connected along a center line to form a cross structure, metal film strips are respectively arranged on the lower surface of a left arm, the upper surface of a right arm, the left side surface of an upper arm and the right side surface of the lower arm of the cross resonance structure. The frequency selection surface structure is applicable to manufacturing and usage of an antenna cover.

Description

technical field [0001] The invention relates to a frequency selective surface structure. Background technique [0002] Frequency Selective Surface (FSS), referred to as FSS, is a single-layer or multi-layer quasi-planar structure composed of a large number of passive resonant units arranged in two-dimensional periodicity on the dielectric layer. The concept of frequency selective surface originated from the research of grating, which was first discovered and proposed by American physicist David Rittenhouse; after years of research and development, frequency selective surface has been widely used in various fields from microwave band to light wave band middle. [0003] In engineering, frequency selective surfaces are widely used, covering many aspects of the electromagnetic field: In the microwave band, frequency selective surfaces are often used as sub-reflectors of reflector antennas to improve the utilization efficiency of reflector antennas. In addition, FSS It is also ...
