Microwave Devices Simulation with Ansoft HFSS

2007 8th International Conference on Electronic Measurement and Instruments, 2007
Some microwave passive devices for applications in microwave moisture content measurement, including waveguide absorption type variable attenuator, optimum H surface horn antenna, optimum pyramidal horn antenna, were simulated by Ansoft's HFSS. Certain targets have been achieved, and it is a new attempt to apply the microwave simulation technology to ...

Overview of Hybrid Solver in HFSS

2018 IEEE International Symposium on Antennas and Propagation & USNC/URSI National Radio Science Meeting, 2018
This paper presents an overview of the hybrid solver in ANSYS HFSS for electrically large radiation and scattering problems. In HFSS v12, a domain decomposition solver was adopted to serve as an effective and parallelizable finite element preconditioner.

The development of HFSS

2016 USNC-URSI Radio Science Meeting, 2016
HFSS was the first general-purpose software product to solve arbitrary three-dimensional electromagnetic field problems. It introduced a number of new technologies in computational electromagnetics including automatic adaptive mesh generation, tangential vector finite elements, transfinite elements, and reduced-order modeling.

3D surface mount component modeling for HFSS

2018 IEEE 19th Wireless and Microwave Technology Conference (WAMICON), 2018
Advances in full-wave three-dimensional electromagnetic simulation and modeling of surface mount components are demonstrated for example coupled multi-layer capacitor and wire wound inductor configurations. Among the advances enabling 3rd party model sharing is the ability to encrypt the proprietary material and geometry properties in ANSYS® HFSS™ that

Modeling phased array antennas in Ansoft HFSS

Proceedings 2000 IEEE International Conference on Phased Array Systems and Technology (Cat. No.00TH8510), 2002
A number of algorithms and procedures have been developed for the commercial 3D finite element solver Ansoft HFSS, to model antennas. Primary among these is the application of periodic boundary conditions and array factors to speed up the simulation of phased arrays.

Design of radar antenna based on HFSS

2017 2nd International Conference on Robotics and Automation Engineering (ICRAE), 2017
In this paper, a millimeter-wave radar array antenna with practical application is designed. According to the requirements of practical application of the speed radar, the actual detection range and return loss characteristics of the radar antenna are very demanding. At this request, the radar antenna array arrangement, through the power distributor to

Calculating slow-wave circuit parameters with HFSS

Abstracts. International Vacuum Electronics Conference 2000 (Cat. No.00EX392), 2002
Slow-wave circuits provide the wave propagation structures for microwave devices such as TWTs, and CFAs. In this paper we show how to use Ansoft HFSS to calculate dispersion relations for slow wave circuits. The technique could also be used to study other periodic structures.

HFSS Simulation of Vacuum Tube RF Power Amplifier

Proceedings of the 2005 Particle Accelerator Conference, 2006
Development and upgrade of rf power amplifiers require comprehensive calculations to predict and optimize various parameters of the system before hardware modifications are applied. ANSOFT HFSS code provides a powerful tool for 3D EM simulation of the amplifier output resonator comprising a vacuum tube as a passive element. Two examples of this kind of

HFSS modeling of cross-coupling in borehole radar

RADAR 2002, 2003
The total cross-coupling between UWB borehole radar antenna slots in a metal drill string were modelled using the high frequency structure simulator (HFSS). Methods of suppressing this coupling were also modelled and provided promising results. Ferrite sleeves were able to provide a 30 dB reduction of cross-coupling levels, and phased pairs of transmit
