FAA-450 Antenna Analyzer (EU1KY) Introduction
I recently received a RF board. It is in the form of a docking board on the
STM32F746 Discovery board.
When you connect the RF board and the STM32F746 Discovery board, they
operate as a very good antenna analyzer.


As well as a general antenna analyzer, it is possible to measure the phase
so that the characteristics of the antenna can be easily grasped.

I accidentally used this antenna analyzer, but it was incredible. So I
decided to analyze this antenna analyzer a little bit more and improve its
functions.
