In this paper a method to derive lumped-element network models for distributed microwave circuits by means of system identification is presented. This procedure has been applied to a 4-port integrated transformer circuit the purpose of which is to feed an on-chip planar dipole antenna for chip-to-chip wireless communication. The resulting network topologies and elements are given and the properties...
A network oriented approach to passive microwave circuits modeling provides compact representation of the circuit and leads to the reduction of the required computer time and memory capacity. The proposed stability criterion allows splitting the simulation results into two parts representing a lumped elements model and distributed parameters model. The system identification procedure has been applied...
The full wave time-domain numerical simulation of the 3-D electromagnetic structure yields wide band reaction of the multiport microwave circuit on the input electromagnetic signal. The realization of the system identification procedure demands the preliminary determination of the late-time border and the order of the pole model. The new criterion for their estimation is offered. This criterion is...
The network oriented representation of the 3-D electromagnetic structures is based on two types of linear systems. The former one is a dynamic linear system which describes the interaction of electric and magnetic fields inside the structure while the latter one is a linear system consisting of delay lines meant for the reflection and propagation. The system identification of the linear dynamic system...
A frequency domain approach to the E-pulse radar target discrimination technique is introduced. This approach allows the interpretation of E-pulse phenomenon via the E-pulse spectrum. The discrete E-pulse and its relation to continuous E-pulse are shown. The addition of extra zeroes to E-pulse structure has been suggested and its influence on the increasing of discrimination accuracy has been proved...
