| Abstract(in English) | This paper proposes a passive network that exhibits a spiral impedance trajectory in frequency response. One loose-coupled transmission line generates a pinwheel locus, and another long transmission line makes the locus revolve in multiple turns around the reference impedance origin. This enables the system’s output impedance to cover a wide range on the Smith Chart. This scheme is quite useful in frequency-diversity impedance matching for RF power systems to excite an unknown or time-varying load. |
