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.

Radiation analysis of embedded capacitor based on HFSS

2015 16th International Conference on Electronic Packaging Technology (ICEPT), 2015
The simulation model of embedded capacitor radiation was established based on HFSS (High Frequency Simulator Structure) software in this paper. Radiation problem of the embedded capacitor at high frequency was studied by the model. Its near-field radiant power gain was obtained and the effects of the variations of the signal frequency, capacitance ...

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 High Frequency Structure Simulator (HFSS). Methods of suppressing this coupling were also modelled and provided promising results. Ferrite sleeves were able to provide a 30dB reduction of cross-coupling levels, and phased pairs of transmit ...

Analysis of Electrical Characteristics of LPDA and HFSS Simulation Design

2011 4th IEEE International Symposium on Microwave, Antenna, Propagation and EMC Technologies for Wireless Communications, 2011
The electrical characteristic of LPDA is analyzed first in this paper. Simulation software HFSS is used to get the optimization design of LPDA, and the simulation results are agree with the experimental dates appropriately. This simulation method uses much less time and cost than traditional method.

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.

Design of a Novel RFID Microstrip Antenna and HFSS Simulation

2016 Sixth International Conference on Instrumentation & Measurement, Computer, Communication and Control (IMCCC), 2016
According to the working principle and the actual correction of the RFID microstrip antenna, this paper designed a new type of rectangular microstrip antenna which worked under the condition of circular polarization, and in this design, the new type of rectangular microstrip antenna is obtained by loading an equal number of rectangular slot in the each

The Optimum Design of PIFA Based on HFSS and Genetic Algorithm

2011 7th International Conference on Wireless Communications, Networking and Mobile Computing, 2011
In this paper we demonstrate the optimization of planar inverted F antenna (PIFA) for broadband operation by optimizing the geometry/size of the inverted-F patch and the position of the shorting pin. The optimization technique based on the combination of Genetic Algorithm(GA) with HFSS is presented to facilitate the PIFA design.

Automation of reflectarrays in HFSS using visual basic scripting

2018 Texas Symposium on Wireless and Microwave Circuits and Systems (WMCS), 2018
High gain, large radiating structures such as multi-element antenna arrays and reflectarrays are finding an increasing number of applications to fulfil the demands of higher capacity and better coverage. For large reflectarrays, number of elements may be more than a thousand.
