Patent ID: 8847846

Claim:
An antenna based on a magnetic pseudo-conductor material, comprising: a ground plane formed of an electrically conductive material; a spiral antenna structure formed over the ground plane and including a magnetic pseudo-conductive material exhibiting a real part of a permeability greater than a corresponding imaginary part of the permeability while the relative permeability is greater than the relative permittivity of the material, the magnetic pseudo-conductive material being shaped to extend from a center into opposite directions as two spiral antenna arms to form as a spiral having two spiral antenna arm tips at two opposite sides of the spiral and to have a spatially varying permeability along each spiral antenna arm between the center and each spiral antenna arm tip; and a transmission line formed near the center of the spiral antenna structure to feed an antenna signal with respect to the spiral structure to enable an antenna operation by the ground plane, the spiral antenna structure and the transmission line.
