Abstract :
Optimized dual signal Impedance Standard Substrate (ISS) designs are demonstrated. The optimal designs had loop-under grounds, were selected for minimum deviation from lumped element behavior and used mode dampening structures. A comparison of existing design approaches is given and the quality of the designs is illustrated to 50 GHz.
