    Abstract: A phase shifting device, an antenna unit and a base station are disclosed. According to an embodiment, the phase shifting device comprises a power divider and a phase shifter. The power divider comprises an input inlet for an input signal, a first output outlet connected with an impedance member having a system impedance, and a second output outlet connected with the phase shifter. The phase shifter comprises a first plate and a second plate slidable relative to the first plate. Two parallel microstrip lines are provided on a first surface of the first plate. An adjusting member is provided on a second surface of the second plate that faces to the first surface of the first plate. The adjusting member is configured to adjust a length of a total signal transmission path that is from one to the other of the two parallel microstrip lines via an intermediate signal transmission path introduced by the adjusting member, or to prohibit the input signal from transmitting to the second output outlet, according to a position of the second plate relative to the first plate when the second plate slides relative to the first plate.

    Abstract: L'invention concerne un dispositif radiofréquence passif (1) corrugué, notamment un guide d'onde ou une antenne de type cornet. Le dispositif (1) comporte une âme (2) comprenant au moins une face interne (4, 5, 6, 7; 12) délimitant un canal (3) pour filtrer et guider les ondes. Ladite au moins une face interne (4, 5, 6, 7; 12) du canal comporte une pluralité de cavités (9) ou de gorges (10). Chaque cavité (9) ou chaque gorge (10) est formée par des parois adjacentes (11a, 11b) substantiellement parallèles afin de filtrer les ondes traversant le canal. Les parois adjacentes (11a, 11b) sont inclinées par rapport à l'axe central du canal (3).

    Abstract: An example balun includes a center conductor that passes through a printed wiring board having multiple dielectric layers and cage vias arranged relative to the center conductor. The cage vias include a first set of cage vias that extend between an unbalanced connection to the balun and a balanced connection to the balun. The first set of cage vias are part of a first circular arc and are connected to electrical ground through a first ground ring. The cage vias include a second set of cage vias that extend from the unbalanced connection part-way through the printed wiring board. The second set of cage vias are part of a second circular arc and are connected to the electrical ground through a second ground ring. The second circular arc is longer than the first circular arc.
