Graphical Investigation of Quantisation Effects of Phase Shifters on Array Patterns

Abstract

This document presents graphical investigations of the array factor of phased arrays with digital phase shifters. A software program based on basic antenna array theory has been developed in Matlab to obtain the main array characteristics (array factor and directivity). The array factors of linear arrays of different sizes with different types of phase shifters have been studied as a function of the number of bits and the frequency. Unconventional two-dimensional colour graphical representations are used to identify some characteristics of the array factor of arrays with digital phase shifters that can not be so clearly and quickly visualised with conventional graphical representations. Particularly, the effects of quantisation on the array factor for arrays of different sizes and for phase shifters with different numbers of bits, over scanning and frequency ranges, are shown using this representation. Numerous data are also provided.
