摘要：
In this paper, the transmission performance of multi-modal orbital angular momentum (OAM) antenna array based on vortex electromagnetic wave (VEMW) are investigated by simulation and measurement. An eight-element circular array antenna with feed network is designed to excite and receive multi-modal vortex wave. Radiation patterns of several modes are simulated and mode isolation at different distances and radii of the array are obtained and compared by methods of adding receiving array and concentric rings. Furthermore, insertion losses are measured for different distance, which show the transmission characteristics of VEMW.
