Uniaxial anisotropy effects on crosspolarisation level of printed dipole in superstrate-substrate configuration

The uniaxial anisotropy effects on the crosspolarisation level (CPL) of a printed dipole in the superstrate-substrate configuration are investigated. It is shown that the substrate anisotropy is more relevant than that of the cover, and is an important parameter to be considered in the design of a low CPL dipole array.
