Some Considerations on Radiation Properties of Antennas Embedded into Low-permittivity Metamaterial
Gain increase and radiation properties of a quarter wavelength monopole, an open rectangular waveguide and a rectangular horn antenna embedded into a low-permittivity wire-based metamaterial are studied. Measurement results confirm that metamaterial used for embedding of the antennas contributes to the increase of the antenna gain. Lower the antenna gain, the gain improvement achieved by the metamaterial slab is larger. The influence of dimensions and thickness of the metamaterial slab on the gain improvement and radiation patterns is investigated. The results show that for thin slabs the gain improvement weakly depends on the slab cross section area, while for thick slabs larger cross section allows significantly better focusing of the radiated waves.
