Introduction

NanoVNA is a simple but powerful tool to analyze antennas.

VNA: Vector Network Analyzer

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.
