    摘要: Der Polarisationswandier besteht aus einem Wellenleiter (1, 13, 14) mit darin längs seiner Achse angeordneten Mitteln, die ein Bezugssystem (x', y') bilden aus senkrecht aufeinanderstehenden Längsschnittebenen, in denen die orthogonalen Komponenten einer in den Wellenleiter eingespeisten Welle unterschiedlich grosse Phasendrehungen erfahren. Um dieses Bezugssystem sehr schnell in jede beliebige Winkellage gegenüber der eingespeisten Welle einstellen bzw. es einer Rotation mit sehr hoher Winkelgeschwindigkeit aussetzen zu können, sind ortsfest um die Wellenleiterachse verteilt steuerbare magnetische und/ oder elektrische Eigenschaften aufweisende Mittel (ferrit (2), Dioden (15, 16, 17, 18) angeordnet, wobei durch Einwirken auf die magnetischen und/oder elektrischen Eigenschaften der einer wählbaren radialen Richtung zugeordneten Mittel das Bezugssystem eine dieser Richtung entsprechende Orientierung erhält.

    摘要: A ferrite scanning line source (100) is formed of a ferrite toroid (102) and one or more dielectric slabs (105, 106) mounted to a side of the toroid (102). A signal propagating through the waveguide is phase shifted by the magnetization of the toroid (102). The further down the toroid the signal propagrates the greater the phase shift that is applied to the signal. Radiators or coupling ports are formed by slots (112) cut in a wall (116) of the waveguide. The phase of the signal radiating from each slot (112) in the line source (100) is shifted from the signal emanating from the preceding and following slot in the line source (100). By properly locating the slots (112) along the line source (100), a composite beam formed by the energy radiating from each slot may be titled to a desired direction.

    摘要: The present invention is for an apparatus and method of fast-switching a dual-toroid microwave ferrite phase shifter. A first circuit 23,24 is provided for controllably switching the ferrite in one of the toroids 9 between a saturated and partially saturated states. A second circuit 25,26 is provided for controllably switching the ferrite in the other of the toroids 12 between a saturated and partially saturated states. A control circuit 19 is provided for controlling the first and second circuits such that the ferrite in at least one of the toroids is maintained in the saturated state at any given time such that any desired phase shift may be achieved with only one switching operation for each toroid. The present invention provides new reference states such that there are two reciprocal phase states for any given phase state such that a reciprocal phase state may always be achieved with only one switching operation for each toroid.

    摘要: A ferrite phase shifter is described in which the switching circuit is arranged to apply a complementary setting pulse to a latching wire (4) of a toroidal ferrite phase shifter (2) before a resetting current pulse is applied by means of a latching wire (6). A new phase state is then set by a normal setting pulse applied to the latching wire (4). The complementary setting pulse is of a voltage sufficient to bring the magnetisation state of the phase shifter to an unsaturated magnetic state. This may be achieved by applying a complementary setting pulse of a voltage which together with the voltage of the previous setting pulse adds up to a constant amount. Alternatively, the magnitude of the complementary setting voltage may be determined on an empirical basis in order to reduce the phase error in any subsequently set phase. This may result in the unsaturated magnetic state varying in dependence on the previously set state.
