Antenna-waveguide microwave devices of carbon composition materials

The fundamental possibility of developing microwave antennas of a carbon composition material is shown. A model specimen of a horn antenna for a range of 5 GHz is made in laboratory conditions from the carbon composition material with a graphene-containing binding substance. The electrodynamic characteristics of the antenna are investigated and compared with characteristics of a metallic antenna with similar geometrical parameters. It is found that the carbon composition antenna is practically identical to its metallic analog, but has superior mechanical parameters.
