摘要：

In this paper, a multi-uniform circular array (M-UCA) antenna is designed at 10GHz for generating multiple orbital angular momentum (OAM) vortex electromagnetic wave. The UCA antenna is constituted by 12 half wave dipoles as array elements and with a circular ground 1/4 wavelength behind the array. Different UCA antennas are designed to generate different OAM modes. The whole aperture sampling receiving (WASR) scheme is adopted to receive the vortex electromagnetic wave. And the parameter mode percent (MP) which is newly defined by ourselves is used to evaluate the OAM mode spectrum. Both the transmission characteristics and OAM mode spectrum of the multiple OAM vortex electromagnetic wave generated by the M-UCA are discussed.
