Installed Performance Modeling & Simulation for Antennas – "A Good Antenna, Righteously Placed"

Speaker: Shawn Carpenter, ANSYS Electronics Business Unit

Presentation

Abstract

The design of successful antennas and antenna systems for coexisting RF sensor and communication systems is a growing challenge for today's multi-function platforms. The design of high-performance antennas may require high frequency electromagnetic analysis over a dimensional range that spans 5 or 6 orders of magnitude and which may include full platforms that extend thousands of electrical wavelengths in size. To accomplish the necessary simulations in an efficient manner—with high fidelity—requires multiple efficient EM simulation solver approaches which must be linked or hybridized for a smooth analysis progression.

ANSYS will present an engineering workflow for synthesizing, optimizing and analyzing the installed performance of high-performance antennas and arrays. The process begins with a solid model antenna synthesis and includes fully automatic hybridization of EM solver technologies that include finite-element method (FEM), Method of Moments (MoM and MLFMM), and Shooting and Bouncing Rays (SBR) to characterize the antenna system in isolation and in its intended installed environment.

Biography

Shawn Carpenter is a Senior Product Manager for RF Products with ANSYS, and has responsibility over product strategy and customer solutions involving installed performance modeling of antennas in electrically large environments, large target radar signature analysis, ADAS and near field radar sensor modeling and RF system cosite interference analysis. Prior to acquisition by ANSYS in 2015, he served as VP of Marketing and Sales for Delcross Technologies. He holds a BSEE from the University of Minnesota and a MSEE from Syracuse University, and has over 27 years of experience in applications, marketing and sales of high frequency electromagnetic and RF system analysis EDA software.

Seminar Participation

Attending In Person

For select seminars, you may wish to attend in-person if you are in the vicinity of NASA Ames Research Center. These AMS seminars are held in Building N258 in Room 127, just off the front lobby. Sessions available to attend in-person will be indicated in the announcement information. In-person participants without NASA badges will need a valid visitor badge (US citizenship or permanent residency is required) to enter the facility.
