Standard Methods for Analyzing Antenna Parameters

This chapter describes methods for measuring selected antenna parameters. These are mainly methods for measuring impedance parameters, measuring antenna radiation patterns and measuring gain. Measurements in antenna technology require a wide range of different measurement methods and instrumentation. Typically, these range from simple measurements such as impedance matching and transmission measurements, to high-resolution radiation pattern measurements and long-range pulse response measurements. Many antenna measurements require shielded anechoic chambers, reflectors, test antennas with known parameters, handling equipment and cost-effective software.
