Abstract
A comparative investigation is performed for examining the radiation characteristics of a dipole antenna array on multilayered bianisotropic substrate with a grounded soft and hard surface possessing certain direction of the conductivity. Eight continuous magnetic groups of symmetries for describing the constitutive features of such bianisotropic structure are considered, respectively. Numerical examples are presented to show the effects resulted from the changing of magnetic groups on the co- and cross-polarized far-field normalized patterns of linear and square dipole antenna arrays. This work provides a basis for understanding the possible differences among various kinds of bianisotropic media.
