Abstract

On the basis of the characteristics of electromagnetic wave orbital angular momentum can improve spectrum efficiency, this paper proposes a low profile, more OAM models design of antenna. The antenna subject selection is made of glass fiber epoxy resin substrate, using phased array feed technology under the condition of the limited antenna unit number achieved by each antenna feed different phase excitation. By adjusting the position of the feeding point, the matching of the input impedance of the antenna is improved and the optimal structure of the antenna is determined. The simulation results show that the antenna achieves good impedance matching at the center frequency of 2.45GHz and generates 7 kinds of vortex electromagnetic beams with different OAM modes. The antenna has the characteristics of small size, light weight and low profile, which provides a novel antenna structure for the design of communication terminal antenna array.
