Abstract:
A thin, broadband balun, comprising:a) a substrate having a first surface and a second surface and a first edge and a second edge; b) a meandering stripline disposed on said first surface and extending from a connection proximate from said first edge to a predefined interior junction point thereupon; c) an open-circuit stripline stub disposed on said first surface and extending radially a predetermined distance from said junction point and being electrically connected to said stripline at said junction point; d) a short-circuited stripline stub disposed on said first surface and extending radially a predetermined distance from said junction point and being electrically connected to said stripline at said junction point; e) a slotline disposed on said second surface for interfacing with an external device, said slotline connecting said junction point and a terminus proximate said second edge; f) an open-circuit slotline stub disposed on said second surface and extending radially a predetermined distance from said junction point and being electrically connected to said slotline at said junction point; and g) a short-circuited slotline stub disposed on said second surface and extending radially a predetermined distance from said junction point and being electrically connected to said slotline at said junction point.
