Abstract

The invention discloses a left-handed material of a plane structure microwave band and relates to the communication field. The left-handed material can solve the problem that the traditional left-handed material is heavy in a structure and inconvenient to manufacture. In comparison with the traditional material, the left-handed material only includes ordinary microwave dielectric slabs and metallic copper, thus it is low in cost, processed by an ordinary PCB (printed circuit board) printing technology, and totally suitable for low-cost mass production. The left-handed material includes n units, wherein n is a positive integer; each unit comprises a copper-coated resonance structure unit and a dielectric slab, the copper-coated resonance structure unit is fixed to the upper surface of the dielectric slab; the copper-coated resonance structure unit is etched with a hollow structure which is composed of a horizontal 'H' structure, two left rectangular openings and two right rectangular openings. The left-handed material is applied to the communication field.

Description

Technical field [0001] The invention relates to the field of communications. Background technique [0002] At present, international scholars collectively refer to materials prepared by artificially designed structures with specific electromagnetic properties as metamaterials. In recent years, people have been particularly interested in this metamaterial because the period length of the metamaterial structure is much smaller than the wavelength of electromagnetic waves, which is conducive to the miniaturization and integration of devices, which is unmatched by ordinary photonic crystals. Metamaterials represented by left-handed materials, photonic crystals, and frequency selective surfaces (FSS) have broad application prospects in optical imaging, miniaturized antennas, electromagnetic wave invisibility and other fields. The planar supernormal medium has a wider application range due to its advantages in planar structure. [0003] The traditional design idea of ​​left-handed mate...
