Abstract

See full text

The present invention discloses an adjustable holographic metamaterial antenna structure, wherein the structure comprises: a surface waveguide feed network configured to connect to a power dividing network; a varactor diode bias circuit configured to comprise a direct current bias circuit and a plurality of varactor diodes associated with the direct current bias circuit; and a metamaterial surface arranged above the direct current bias circuit, and the metamaterial surface and the direct current bias circuit are connected through a bias via hole; wherein the metamaterial surface and the direct current bias circuit separately perform direct current bias feeding on each of the varactor diodes, and an interference pattern of the metamaterial surface is changed to achieve scanning of a radiation pattern. The present invention solves the problems that a two-dimensional feed network layout of a holographic-metamaterial antenna is difficult and is easy to interfere with radio frequency signals.
