For the purpose of utilizing orbital angular momentum (OAM) carrying beams, multiple OAM beams should be generated preferably by a single antenna. In this paper, an OAM mode reconfigurable antenna is proposed. The proposed antenna can be used to transmit mode 1 and mode −1 OAM beams respectively by controlling PIN diodes on the feeding network. The simulation results such as return loss, near-field and far-field phase patterns, radiation patterns of two operating states for mode 1 and mode −1 are given. The proposed antenna can serve as a candidate for increasing the link capacity at 2.4 GHz.
