Abstract (en)
[origin: US2017373382A1] An antenna includes one or more elementary antennas with non-coplanar planar loops extending about a main axis in respective inclined planes. Each elementary antenna is formed by tracks of a structure printed on a circuit support extending in the inclined plane, with two imbricated planar loops tuned on frequencies includes in two respective distinct WiFi frequency bands. With a flexible circuit support, an antenna housing of the drone includes a conformed hollow cavity comprising a plurality of inclined planar faces, which are the counterparts of the inclined planes of the elementary antennas, against which bear these latter after deformation of the flexible support.
Abstract (fr)
Cette antenne (100) comprend une pluralité d'antennes élémentaires (102) avec des boucles planes non coplanaires s'étendant autour d'un axe principal dans des plans respectifs inclinés. Chaque antenne élémentaire (102) est formée par des pistes d'une structure imprimée sur un support de circuit (124) s'étendant suivant le plan incliné, avec deux boucles planes imbriquées accordées sur des fréquences comprises dans deux bandes de fréquences WiFi respectives distinctes. Avec un support de circuit (124) flexible, un logement d'antenne (26) du drone comprend une empreinte creuse conformée avec une pluralité de faces planes inclinées (28), homologues des plans inclinés des antennes élémentaires (102), contre lesquelles viennent en appui celles-ci après déformation du support flexible.
