Title
(EN) RADIATION SHIELDING AND RANGE EXTENDING ANTENNA ASSEMBLY
(FR) ENSEMBLE ANTENNE A BLINDAGE CONTRE LES RAYONNEMENTS ET ETENDANT LA PORTEE
Abstract
(EN)
An antenna assembly for a radio transmitting device (10) includes a radiation absorber (80) defining an open curved shape in cross section, so as to define an open transmission area. A driven antenna (40) is disposed adjacent to the open transmission area so that during use some of the radiation emitted from the antenna (40) is absorbed by the radiation absorber (80). At least one parasitic radiation redirection element (322) receives radiation emitted from the antenna (40). The parasitic radiation redirection element (322) directs a portion of the radio signal toward the open transmission area, so as to extend a transmission of the radio signal transmitting device (10).
(FR)
Ensemble antenne pour un appareil émetteur (10), comprenant un absorbeur de rayonnements (80) dont la section transversale a une forme incurvée ouverte définissant une zone de transmission ouverte. Une antenne à attaque directe (40) est placée à proximité de la zone de transmission ouverte de sorte que pendant l'utilisation une partie du signal rayonné émis par l'antenne (40) est absorbé par l'absorbeur de rayonnements. Le signal rayonné qui n'est pas absorbé par l'absorbeur de rayonnements (80). Au moins un élément de redirection de rayonnement parasite (322) reçoit le rayonnement émis par l'antenne (40). L'élément de redirection de rayonnement parasite (322) dirige une partie du signal radio vers la zone de transmission ouverte, de manière à étendre la portée de transmission de l'appareil radioémetteur (10).
