A miniature patch antenna for handset mobile communication is studied by loading an H-shaped patch associated with fashionable mushroom structures. The mushroom structures work as effective high index metamaterials while the H-shape can lengthen the current path on the patch. They both contribute to reduce the patch length. To verify the conceptual method, an H-shaped patch meta-antenna is demonstrated in full wave simulations and experiments. Good agreement has been observed. A compact patch is achieved for the antenna with a size of 0.15λ0×0.15λ0. The measured antenna gain is acceptably high as 4.2 dBi.
