Engineers often turn to VNAs to measure the return-loss characteristics of an antenna, but they must be used carefully ...

If anything about electronics approaches the level of black magic, it’s antenna theory ... And with good reason; while not a full vector network analyzer (VNA) that will blow a multi-thousand ...

The antenna in question is a loop antenna. He uses a professional VNA (Vector Network Analyzer) but you could get away with a hobby-grade VNA, too. The software for simulation is 4NEC2.

Rohde & Schwarz has expanded its vector network analyzer portfolio with the R&S ZNB3000, which offers best-in-class radio frequency (RF) performance. It combines high measurement accuracy with ...
