Antenna Design and NanoVNA
From wikiluntti
Introduction
NanoVNA is a simple but powerful tool to analyze antennas.
VNA:
SWR: Standing Wave Ratio measures the degree of mismatch between a transmission line and its load. SWR is a measure of what is happening to the forward and reflected voltage waveforms and how they compare in size.
Theory
Calibration
NanoVNA should be calibrated
Antenna Measurements
Use Port 1 when measuring one port devices.
NanoVNA draws the measurement result on the screen as a graph of the measured quantity versus frequency or on the Smith Chart.
