One-port VNA Breadboard for Antenna Reflectometer

  • Designed originally for a firmware program that used a multiplexed ADC.
  • I improved the calibration using Short/Short/Match method of calibration over the original firmware method.
  • Debugged firmware/DSP
  • Showing the phase at different frequencies at different reflector distances in the near field of the antenna.
  • Rewrote firmware for an MCU with a high sample rate ADC
VNA breadboard assembled using semflex
