Extrapolation range measurements that unlock accurate antenna gain and polarization
This guide explains how to determine an antenna's power gain and polarization at reduced range distances, using a generalized three-antenna method. It covers theory, measurement procedures, range setup, and instrumentation, with practical steps to achieve high accuracy without large testing sites.
This edition also discusses extensions for swept and stepped frequency gain calibrations and methods to correct for ground reflections, helping you manage near-field and multipath effects that can affect results.
- How to configure a measurement range and align antennas for precise data
- Procedures for amplitude, phase, and distance measurements across frequencies
- Techniques for error analysis and improving repeatability to ±0.1 dB or better
- Approaches to swept-frequency and near-field corrections that support advanced calibrations
Ideal for engineers and technicians calibrating antenna standards and evaluating performance across communication, radar, and remote-sensing systems.
