Automated Pattern Measurement for Circularly-polarized Antennas Using the Phase-amplitude Method

This article describes an increasingly popular procedure for measuring circularly-polarized (CP) antennas. Known as the phase-amplitude method, this procedure is particularly well suited for implementation in an automated antenna measurement system tha...
Polarization is a basic consideration in the design of any wireless communication system. Most systems use either linear or circular polarization. For a simple description of these two types of wave polarization, consider the illustration shown in Figure 1 . This figure shows an electromagnetic wave approaching an observer....
