Antenna Modeling Seminar
Sunday - 1/2 Day

8:00 AM - 12:00 PM

Contra Costa, Salon 2



Steve Stearns, K6IOK, will present Pacificon's first ever 1/2 day seminar on the software modeling of antennas. Sunday morning in the San Ramon Boardroom.

Topics will include:
  • Antenna modeling,
  • Software tools,
  • Specifying a model,
  • Calculating far field patterns,
  • Calculating near fields,
  • Calculating impedance,
  • Using E&M optimizers to find the best geometry,
  • How to export and transfer impedance data between programs,
  • Impedance match network design,
  • Using circuit optimizers to find the best design.
