Abstract In this paper small sized antenna are considered, based on the use of metamaterials. The physical reasons explaining the effects of directivity increasing and antenna matching improvement are analyzed. It is shown that the achievement of beneficial effects that are discussed in known publications as a consequence of the properties of metamaterials with negative permittivity and permeability can be explained in terms of a standard and implemented means.

Key words: small sized antennas, antenna  matching, antenna directivity, metamaterials.
