In this paper we propose a broadband equivalent circuit model of coupled integrated antennas using a generalized Foster approach. A large-signal multi-harmonic X-parameter model representation of On-Chip Schottky Diodes is derived for effective Antenna-Detector Co-Simulation, Co-Design and Co-Verification. Concurrent optimization of the Schottky Diode arrays geometry and large-signal electrical performances...
Traditionally emission measurements are carried out in frequency domain using pre- and final scans. Time-domain EMI measurement systems allow to reduce the scan time by orders of magnitude, enabling novel test methods. In this paper the measurement uncertainty for intermittent signals during pre-and final scans is investigated. The effect of the dwell time on the measurement accuracy in the peak and...
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...
We present a novel planar multilayered cylindrical reflector antenna for ultra wide band (UWB) applications. An UWB radiating element with an impedance bandwidth from 3-21 GHz is designed using a genetic algorithm (GA) in connection with method of moments (MoM). To achieve compact size and unidirectional radiation characteristics the antenna is embedded into a dielectric substrate-superstrates multilayered...
