N2 - In this letter, a compact beamsteering multiple-input-multiple-output (MIMO) antenna is proposed for directional modulation applications. A generalization of the beamsteering principle is presented and by exploiting the antenna's unidirectional beamsteering capability within the entire azimuth plane, the system realizes secure steerable transmissions in the direction of the legitimate receiver, with a low bit error rate of 10-5, while a high error rate of 10-1 is seen outside the desired regions. Numerical and experimental verifications are carried out to validate the proposed concept and comparisons with circular arrays are conducted, revealing that the system achieves comparable performance but with up to 35% and 71% reduction in antenna diameter and profile, respectively. The method is proposed as a good candidate to enhance the security of small Internet of Things (IoT) devices.
