Abstract

Abstract : A modified uniform circular array is analysed and configured to generate radio waves carrying orbital angular momentum (OAM). The relationship between OAM mode and array parameters is derived mathematically. Results show that the produced OAM mode can be altered arbitrarily by changing the exciting frequency when the array is fixed. Moreover, the OAM mode is associated with elevation angle, offering the potential of elevation resolution for radar imaging.
