MM-wave left-handed transmission line antenna on anisotropic substrate

The paper present a mm-wave metamaterial CoPlanar Waveguide Zeroth-Order Resonating antenna on magnetically biased ferrite substrate. The measurements demonstrate affecting of the antenna resonant frequency, return loss and radiation characteristic depending on the strength of biasing magnetic field. The resonant frequency shifts of about 1.1 GHz for magnetic biasing field variation between 0 T and 0.265 T. The return loss is reduced following magnetic biasing as result of elimination of ferrite low field loss. The radiation characteristic steers between approx. -15° ... +14° depending on the magnetic field strength. The gain is 4.16 dBi and remains almost unchanged following magnetically biasing of the substrate.
