Suppression of surface wave in printed antennas by using a uniaxially conducting cover layer

In this paper, we present a new printed antenna design with a uniaxially conducting cover layer. The surface-wave suppression condition is established by using the transverse resonance technique. The radiation efficiency of the proposed design is computed by performing Fourier space-spectral integration and residue calculus. By properly adjusting the parameters of the multilayered design, the surface-wave power can be completely eliminated at the design frequency. The required design conditions and useful practical guidelines are given.
