In this paper, we investigate multi-antenna covert communications, where the transmitter Alice equips multiple antennas, the legitimate receiver Bob and the eavesdropper Willie equips single antenna. Through analyzing the detection performance and the covert rate, we prove that a positive covert rate is achievable with a certain number of antennas in Alice. Numerical results are shown to illustrate the correctness of our results and the performance of MISO covert communication.
