Title
(EN) PRINTED MONOPOLE ANTENNA
(FR) ANTENNE UNIPOLAIRE IMPRIMEE
Abstract
(EN)
The printed monopole antenna having a printed circuit board (12) with a first side and a second side, a monopole radiating element comprising a first conductive trace (18) formed on the printed circuit board first side, and a conductive element comprising a second conductive trace (20) formed on the printed circuit board adjacent the first conductive trace. The second conductive trace (20) defines and extended ground plane which prevents the radiation of currents from that portion of the first conductive trace aligned with the second conductive trace. The second conductive trace may be formed on either side of the printed circuit board. The printed monopole antenna may be modified to operate within two separate frequency bandwidths.
(FR)
Antenne unipolaire imprimée comprenant une carte à circuit imprimé (12) présentant une première face et une seconde face, un élément rayonnant unipolaire comprenant un premier ruban conducteur (18) formé sur la première face de la carte à circuit imprimé, et un élément conducteur comprenant un second ruban conducteur (20) formé sur la carte à circuit imprimé, adjacent au premier ruban conducteur. Le second ruban conducteur (20) définit un réseau de terre prolongé empêchant le rayonnement de courant à partir de la partie du premier ruban conducteur alignée avec le second ruban conducteur. Le second ruban conducteur peut être formé sur n'importe quelle face de la carte à circuit imprimé. L'antenne unipolaire imprimée peut être modifiée afin de fonctionner dans deux largeurs de bandes de fréquences séparées.
