Abstract
The present disclosure belongs to the technical field of OAM antennas, and provides a frequency re-configurable OAM antenna in S band and a frequency reconfiguration method. The OAM antenna includes a lower dielectric substrate and multiple array units. Each array unit includes a metal patch, an upper dielectric substrate, an outer loop, an inner loop, a coaxial feeder, four metal probes, and four diodes. In the present disclosure, bias states of all the diodes of each array unit are controlled by applying a voltage; when all the diodes are in forward bias states, the antenna works at a high frequency; and when all the diodes are in reverse bias states, the antenna works at a low frequency. The frequency re-configurable OAM antenna in S band in the present disclosure has features of frequency reconfiguration and two OAM radiation modes, and has a stable gain over a broadband.
