Abstract : Digital simulation is used to study a particular configuration of a circularly disposed antenna array. The configuration considered here consists of two banks of the same thirty-two antenna elements. Appropriate delays are added to the signals to first transform the circular array of antenna elements into a linear array. Thus, the two banks at this point consist of two colinear arrays. These can then be squinted to various angles by introducing suitable additional delays. The results show the amplitude of the sum patterns, difference patterns, and the differential phase between the two banks as functions of the squint angle of the linear arrays, the incoming signal elevation, and the incoming signal frequency.
