  • High efficiency short backfire antenna using anisotropic impedance walls
    Patent number: 10320085
    Abstract: A high efficiency short backfire antenna (SBFA) includes a cylindrical reflector and a feed structure. The conductive cylindrical reflector is configured to collect or to radiate electromagnetic waves. The cylindrical reflector has a reflector base and a reflector wall. The feed structure is electromagnetically coupled to the cylindrical reflector. The reflector wall includes a dielectric liner formed on an inside surface of the cylindrical reflector, and the dielectric liner is covered with a structured anisotropic impedance surface.
