Co-simulation of Ansoft Designer and HFSS software is described.

Simulated by HFSS-software,which greatly improves the efficiency and accuracy of t.

A computer-aided design of cylinder combline bandpass filters, which has a good out of band performance, is described based on the equivalent-circuit-method and HFSS-software.

Using Ansoft HFSS software,this paper simulates and discusses the effect of crack defect on stealth performance based on radar cross section (RCS) simulating calculation.

Assisted by Agilent s ADS software simulation platform,a complete satellite communication link was built up through hardware-in-the-loop simulation system connected with testing instrument seamlessly.

Then the process of how to simulate and design the synthesizer with ADS software from Agilent technologies is introduced in detail.

This paper emphasizes the model analysis and the simulation and optimization practiced through applying the ADS software.

The ADS software simulation results show that the design can be directly applied to the wireless communication system compatible.

The following performance of the desinged filter is verified by the simulation re- suits obtained with the software ADS2001:the center frequency of C1,the flat passband response in de- sired bandwidth of 80MHz,the low noise figure of 1.

The transmission line loss of the coplanar waveguide (CPW) and the equivalent circuit model of the microelectromechanical systems (MEMS) switch are simulated using Agilent ADS software.
