Electrically thin magnetodielectric metamaterial fresnel lens antenna
An electrically thin magnetodielectric Fresnel zone lens fed with a patch antenna is presented. By using impedance matched magnetodielectric materials to form the lens, the desired focusing can be obtained with very little mismatch loss. The presented lens thickness is one tenth of a wavelength with alternating regions of free space and material with a refractive index of 6. A metamaterial unit cell composed of capacitively loaded split ring resonators is also presented that is capable of achieving the desired low loss, magnetodielectric response.
