Epsilon-near-zero metamaterial antenna and design method therefor

Abstract

The present application relates to the field of communication technology, and in particular to an epsilon-near-zero metamaterial antenna and its design method. The epsilon-near-zero metamaterial antenna includes a first radiator, a second radiator, and a metamaterial structure; the metamaterial structure is arranged between the first radiator and the second radiator, and includes multiple metamaterial units, each of which is composed of a dielectric unit and a metal wire unit; and the metamaterial structure is used to generate electrical resonance in a preset direction to achieve a target near-zero permittivity in a preset communication frequency band. In the epsilon-near-zero metamaterial antenna described in the present application, by arranging a metamaterial structure between the first radiator and the second radiator, the isolation degree between the first radiator and the second radiator is increased, thereby reducing the coupling between the first radiator and the second radiator, especially in the near-field.
