Abstract

A planar antenna with widened bandwidth comprises at least one first conducting element disposed above an earth plane and separated from the latter, and means for exciting said at least first conducting element, configured to excite two distinct orthogonal resonant modes, wherein said at least first conducting element is embodied by a substrate comprising at least one thin layer of an anisotropic material with relative permeability of greater than 10 for 2 GHz. The antenna applies notably to mobile communications terminals.
