Abstract

Selon l'invention, une antenne bi-bande comprend une couche conductrice plane comportant une région conductrice et une région non conductrice centrale. La région conductrice et la région non conductrice définissent ensemble une paire de structures à fente en F interconnectées, et une structure de ruban cadre couplée à et disposée autour des structures d'antenne à plaque à fente en F.
