The Connecticut Power Electronics Soceity (PELS) and joint chapter on Antennas and Propagation, Microwave Theory and Techniques, and Ultrasonics, Ferroelectrics, and Frequency Control are pleased to bring you an exciting webinar presented by Charlotte Blair and Brian Walker on antenna simulation and measurement. Topics such as measurement fundamentals with a VNA are discussed as well as topics such as measuring gains and shielding effectiveness. 

Charlotte Blair of Ansys will begin the event by presenting on the key considerations when simulating antennas. 

Brian Walker of Copper Mountain Technologies will present on the theory and technical considerations when making measurements with a VNA.

Brian Walker of Copper Mountain Technologies

Topic:

Antenna Measurement and Theory

Biography:

Brian Walker is the Senior RF Engineer, SME at Copper Mountain Technologies. He helps customers resolve technical issues and develops new solutions for VNA applications in test and measurement. Previously, he was the Manager of RF design at Bird Electronics, where he directed a team of RF Designers and created new and innovative products. Prior to that, he worked for the Motorola Component Products Group and was responsible for the design of ceramic comb-line filters for communications devices. Brian is a Senior Member of the IEEE, graduated from the University of New Mexico, has 40 years of RF Design experience, and has authored 3 U.S. Patents.

Charlotte Blair of Ansys

Topic:

Considerations of Antenna Simulations

Biography:

Charlotte Blair, PhD. is a Technical Support Manager for ANSYS Inc. She received her BS in Electrical Engineering at Rutgers-College of Engineering and her MS and Ph.D. in Electrical Engineering from New Jersey Institute of Technology. She has supported electromagnetics simulations using industry known tools for over fifteen years. Her real world experience extends from the design of laser diode transmit modules for Lytel/Lockheed to design of filters for wireless communications applications at Celwave/RFS. She is a professional, self-motivated team player committed to excellence with hands-on RF, microwave, and laser-optic experience; strong field service, customer service, project management and communication skills.


With Maryam Rahmani, Charlotte served as the Technical Co-Chair for the 2016 and 2017 IEEE R1 & R2 Women in Engineering (WIE) Forum East and as Conference Chair in 2018. Charlotte also serves as the IEEE Connecticut Section Chair for the local Microwave Theory and Techniques Society (MTT-S) and WIE Chapter as well as the IEEE Region 1 Women in Engineering Chair.






Agenda

John Noon, chair of the CT PELS chapter will begin the webinar with brief opening remarks. 

Charlotte Blair of Ansys and chair of the CT APP/MTT/UFFC chapter will then present on the challenges and key considerations when simulating antennas. 

Then, Brian Walker of Copper Mountain Technologies will present on the topic of antenna measurements. Brian's presentation outline is as follows:

    • Near and Far Fields
    • Impedance
    • Bandwidth

  • The VNA measurement device

    • What is it?
    • How does it work?
    • Why do we need it?

  • Measuring Antenna Gain

    • Ref Antenna
    • Three Antenna method

  • Near and Far Fields
  • Return Loss, VSWR and Bandwidth
  • “Hot” Antenna Measurement
  • What kind of VNA is needed?
