Dielectric line switch and antenna device

摘要

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 (11, 12) and a plurality of primary radiators are provided on a rotary unit. With the rotation of the rotary unit, the dielectric lines (11, 12) 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. <IMAGE>
