  • Patent number: 12074384
    Abstract: 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.

  • Patent number: 11728575
    Abstract: The present application discloses a VICTS antenna based on an RGW structure, comprising an RGW feeding layer and a radiation layer arranged in sequence, wherein the RGW feeding layer comprises an RGW power splitter and a dielectric substrate for slow wave design, and the RGW power splitter is arranged under the dielectric substrate, wherein a power splitting network cover plate is arranged between the RGW feeding layer and the radiation layer, wherein the RGW power splitter comprises a feeding network and a waveguide feeding port, through which signals are input into the feeding network; the radiation layer is composed of a plurality of CTS arrays. During signal transmission, the signals are input into the feeding network through the waveguide port, and then the signals are fed into each CTS array by the feeding network; the radiation layer is configured to rotate.
