Discover a design workflow for electrically small antennas, with a focus on the reliability of the design procedure.

Electrically small antennas are a crucial part of portable battery-supplied devices. However, they pose considerable design challenges as they are inherently narrowband structures which are sensitive to objects in their vicinity such as housing, batteries, cables or PCBs.

This eSeminar will present the design workflow for electrically small antennas, with a focus on the reliability of the design procedure. Typical design workflows using measurement by semi-rigid cables often lead to an unreliable design which means that the antenna needs to be experimentally tuned. The same applies to naive model simulation when simulation has been attempted with insufficient input detail.

With this eSeminar, explore:

  • Environmental effects on the measurement
  • The use of both vendor datasheet material properties and SMD component models for the matching circuit
  • A modified design workflow which uses both measurements and simulation in CST Studio Suite® 

About the presenter

Jan Eichler is a SIMULIA Solution Consultant Specialist. His main area of work involves high frequency applications and EMC/EMI simulation. He also works on development of techniques to characterize material properties from measured data. Eichler received his M.Sc. and Ph.D. in radioelectronics from the Czech Technical University in Prague in 2010 and 2014 respectively. His research there was focused on antenna modal decomposition and integral equations in electromagnetics.
