Abstract
The device, a conformal antenna, includes an antenna element directly coupled to a layer of gyrotropic material and means for creating a magnetic field, the magnetic field having a component substantially perpendicular to, and passing through, the layer of gyrotropic material and the antenna element. The gyrotropic material may be at least partially disposed on a ground plane and may comprise a material such as yttrium iron garnet. The means for creating a magnetic field can be located within the layer of gyrotropic material and may comprise at least one external magnet. The reflective metal ground plane can be the outer surface of a vehicle. The antenna element could have a dipole antenna configuration, and can produce a wave that is linearly polarized. The operation of the device may be at or above the resonant frequency of the gyrotropic material.
