The antenna device comprises, on a substrate, a plurality of radiating elements and one pair of input terminals for high frequency electrical signals for each of the said elements. Each of the said radiating elements comprises a spiral portion (SPi), and has an extension (PB1i, PB2i) of the stems of its spiral having geometric characteristics different from those of the said spiral, to form for example a peripheral crown (CP) around the latter.
Le dispositif d'antennes comprend, sur un substrat, une
pluralité d'éléments rayonnants et une paire de bornes
d'alimentation en signaux électriques haute fréquence pour
chacun de ces éléments. Chacun de ces éléments rayonnants
comporte une zone conformée en spirale (SPi), et possède
un prolongement (PBli, PB2i) des brins de sa spirale ayant
des caractéristiques géométriques différentes de celles
de ladite spirale, pour former par exemple une couronne
périphérique (CP) entourant ces dernières.
