Uniaxial anisotropic material obtained by parallel layers of two different dielectrics is used to obtain a cylindrical dielectric resonator antenna (CDRA). As a consequence of the anisotropy, the boresight gain of the antenna is increased. The effect of the height-to-radius ratio on the boresight gain variation is also investigated. It is shown that by increasing this ratio, the directivity of the antenna in the boresight direction can be increased. A prototype of the anisotropic CDRA is fabricated and measured. A reasonable agreement between the simulated and measured results is attained.
