| 20140049339 | PLANAR TRANSMISSION-LINE INTERCONNECTION AND TRANSITION STRUCTURES - A combiner/divider circuit may include a plurality of planar transmission lines that each may have a planar signal conductor and at least a planar signal-return conductor. Ends of different ones of the signal conductors of the plurality of transmission lines may interconnect with the signal conductor of a first transmission line may be connected to the signal conductors of second and third transmission lines. Signal-return conductors of the first, fourth, and fifth transmission lines may be connected along their lengths. Vias may connect signal-return conductors of the second and third transmission lines with respective signal conductors of the fourth and fifth transmission lines. The positions of the fourth and fifth striplines relative to the first strip line may reverse in a transition region spaced from the connection region. | 02-20-2014 |
