Abstract: The present disclosure provides a unipolar MIMO antenna, which consists of a plurality of unipolar RF antennae. Each of the unipolar RF antennae comprises a metal sheet and a feeder line. The metal sheet is enchased with a metal microstructure thereon, and the feeder line and the metal sheet are connected in a signal communicative manner. The unipolar MIMO antenna of the present disclosure breaks through the framework of the conventional antenna design and eliminates the complex design of the impedance matching network to ensure miniaturization of the antenna. Thereby, the antenna can be used in a wireless apparatus having a small size, a high transmission efficiency and a high isolation degree among antennae and can satisfy the requirement of a low power consumption in the design of modern communication systems. Additionally, the present disclosure further provides a bipolar MIMO antenna and a hybrid MIMO antenna.

The complementary metamaterial resonant elements may include Babinet complements of “split ring resonator” (SRR) and “electric LC” (ELC) metamaterial elements. In some approaches, the complementary metamaterial elements are embedded in the bounding surfaces of planar waveguides, e.g. to implement waveguide based gradient index lenses for beam steering/focusing devices, antenna array feed structures, etc.
