An anisotropic dielectric realized by layered ceramic structures was adopted to design a low cross-polarization C-shaped patch antenna. The anisotropic dielectric performs as a substrate and can cause additional cross-polarized fields which are able to cancel the cross-polarized fields generated by the C-shaped patch itself, and then reduce the cross-polarization level. Compared to the C-shaped patch antenna with an isotropic substrate, the cross-polarization of the proposed antenna is suppressed by more than 15[Formula: see text]dB with a little gain enhancement at 2.4[Formula: see text]GHz. The anisotropic dielectric has a little impact on the direction of the C-shaped patch antenna. The gain of the proposed C-shaped patch antenna is 6.8[Formula: see text]dB with a cross-polarization of [Formula: see text]28[Formula: see text]dB.
