Increasing the supergain of electrically small antennas using metamaterials

Abstract

Uzkov's determination of the maximum possible directivity (N<sup>2</sup>) of N isotropic acoustic radiators is generalized to antenna elements with the radiation patterns of crossed electric and magnetic dipoles (Huygens sources). In particular, it is shown that resonant Huygens-source elements forming an electrically small two-element parasitic (Yagi-like… (More)
