We analyze some canonical low-profile electromagnetic radiators in the presence of "isoimpedance" substrates configured as anisotropic metamaterials having constitutive tensors that are impedance-matched to free space for all incidence angles. The metamaterials considered here are devised to increase the electrical thickness of the substrate without producing surface waves. We study the effect of such metamaterial substrates on basic properties such as input impedance, return loss, and radiation pattern.
