CA 2251111

A dielectric line switch is provided which is capable of easily controlling the propagation of an electro-magnetic wave. Also provided is an antenna device employing said dielectric line switch. As an embodiment of the invention, a plurality of dielectric lines and a plurality of primary radiators are provided on a rotary unit. With the rotation of the rotary unit, the dielectric lines are switched ON and OFF by virtue of mechanical means, so that a desired change-over may be effected among the plurality of primary radiators in a time sharing manner, and the positions of the primary radiators may be shifted within a plane of the focal point of a dielectric lens, thereby enabling the transmission wave beam and/or reception wave beam to scan in a desired manner.

L'invention est un commutateur de lignes diélectriques qui peut facilement contrôler la propagation des ondes électromagnétique. Une antenne utilisant ce commutateur de lignes diélectriques est également divulguée. Dans l'une des concrétisation de l'invention, une pluralité de lignes diélectriques et une pluralité de radiateurs primaires sont installées sur une unité tournante. Quand celle-ci est en rotation, les lignes diélectriques sont mises sous tension et hors tension par un dispositif mécanique de façon à obtenir un passage désiré ordonnancé dans le temps entre les radiateurs primaires de la pluralité de radiateurs primaires en cause, les positions de ces radiateurs primaires pouvant être décalées dans le plan focal d'une lentille diélectrique, permettant ainsi au faisceau d'émission et/ou au faisceau de réception de réaliser le balayage désiré.
