Lowpass Filter Design by Circuit-EM Co-simulation

Microwave filter is a two port network providing signal transmission at passband and signal reflection or signal absorption at stop-band. Microwave filters are widely used in various microwave systems (radar, radio astronomy systems, base stations…). The topic of this paper is to present various possible approaches to filter design provided by WIPL-D software on a simple example. Filter Designer is a user-friendly, wizard-style application with straightforward two-stage approach to filter design. It is intended for automated design of lowpass, highpass, bandpass and bandstop filters of Chebyshev and Butterworth type... read more

Effective Antenna Design Using EM and Circuit Co-Simulation in WIPL-D Microwave

The EM simulation of complex antenna systems presents a challenge for modern computational software. The goal of a circuit-EM co-simulation is to alleviate the computational complexity decomposing the complete system into parts that need to be simulated using full-wave approach, and parts that would be modeled by predefined library components. Encapsulation of proven parameterized antenna models and their reuse within the same or another project is essential in rapid development of complex systems. ... read more
