Abstract
An FET active slot-ring antenna is used to demonstrate a time-domain diakoptics analysis of a mixed linear/non-linear circuit using the FDTD method. A novel algorithm for includ'ing a non-linear FET connected across a slotline into the FDTD computation is used to simulate large-signal active circuit behaviour. A current excitation technique which allows the source to be transparent to reflected waves is used to launch continuous time domain signals. Experimental agreement with the numerical result is achieved which confirms the accuracy of the analysis method used in this paper.Keywords
