Abstract
A pick-up for electromagnetic energy radiation guided between at least two parallel ground plates includes a plane conductive tongue positioned between the two ground plates in a plane parallel to these plates and pointed in the direction of propagation of the guided electromagnetic energy, and obstacles interposed between the ground plates and the tongue converting the electromagnetic energy guided between the two ground plates, propagated in transverse electromagnetic mode, into an electromagnetic energy that is propagated in transverse asymmetrical electromagnetic mode in a strip line structure formed by the tongue and the two ground plates.
