A time-reversal (TR) multi-channel transmission approach with only one receiving antenna is theoretically proposed, numerically analyzed, and experimentally demonstrated in this paper. By using a single receiving antenna with parallel or serial constructed post-channel circuits, information can be received independently from each receiving channel in the proposed TR system. The simulated and experimented results show that the proposed TR system with a single receiving antenna has similar parallel transmission performance to the traditional TR system with multiple receiving antennas. The proposed approach can be used in the TR high-capacity communication systems.
