A new coaxial–radial transmission‐line junction is proposed and characterized by a rigorous full‐wave modal‐expansion method. The proposed structure modifies the conventional coaxial–radial junction by introducing a circular disk on the top plate of the radial transmission line whose parameters can be adjusted for broadband matchings. Two examples are presented to demonstrate the junction's practicality. ©1999 John Wiley & Sons, Inc. Microwave Opt Technol Lett 22: 87–90, 1999.
