Abstract
The antenna device comprises, on a substrate, a plurality of radiating elements and a pair of terminals for the supply of high-frequency electrical signals for each one of these elements. Each one of these radiating elements comprises a zone of spiral configuration (SPi), and possesses an extension (PB1i, PB2i) of the strands of its spiral having geometric characteristics different from those of said spiral, to form, for example, a peripheral ring (CP) surrounding the latter.
