Abstract

In this paper, an uniform circular antenna (UCA) at 10GHz is designed for generating the multiple orbital angular momentum (OAM) vortex electromagnetic wave. The excitation tolerance of both amplitude and phase of the array element are analyzed. First the characteristics of the OAM vortex electromagnetic (EM) wave including both electric field amplitude distribution and phase distribution are analyzed. Then the whole aperture sampling receiving (WASR) scheme is adopted for OAM mode performance analysis. And a parameter is defined as mode percent (MP) for estimating the performance or mode purity of the OAM vortex EM wave. All these analyses include both the cases of single OAM mode and multiple OAM mode. Finally some conclusions are presented about the UCA excitation design for OAM vortex EM wave generation and reception. This work can be beneficial to the UCA antenna design and OAM vortex generation and application.
