Abstract
An impedance matching stripline transition for microwave signals which are conducted from a stripline circuit on one laminate (2) to another laminate (4) through a number of intermediate laminates (3). The connection between an incoming stripline circuit (21) on one laminate (2) to the outgoing stripline circuit (41) on the other laminate is performed as a short coaxial line. The outer conductor of the coaxial line is formed by a number of through-plated holes (12, 13, 23, 33, 43) in horseshoe form around a central conductor of through-plated holes (24, 34). The outer conductor is connected with the ground plane (31, 11, 45) of the laminates. They serve simultaneously as a suppressor of undesired modes in the microwave signals which are supplied to the transition via the conductor (21).
