“…It then uses phase compensations dependent on the desired secure direction of the legitimate user, and a random number n corresponding to the antenna port used for signal transmission (see [15] for a detailed discussion of the scheme). The method then offers several advantages compared to [11], [12], e.g. : no excessive artificial noise is generated in the directions where the illegitimate users are, which reduces interference with legitimate users present in other systems.…”

This work proposes an energy-efficient Directional Modulation (DM) scheme for on-body Internet of Things (IoT) devices. DM performance is tested using a 5-port stacked-patch MIMO antenna under two scenarios: free space case and using a four-layer human forearm phantom to simulate the user's wrist. It is demonstrated that the scheme achieves steerable secure transmissions across the entire horizontal plane. With low Bit Error Rate (BER) of 1.5 × 10 −5 at the desired directions, eavesdroppers experience a high error rate of up to 0.498. Furthermore, this work investigates the DM performance using a subset of the stacked patches in the MIMO antenna, revealing that some combinations achieve a low BER performance using a lower antenna profile, albeit high side-lobes of BER< 10 −2 seen outside the desired region. Overall, the solution is proposed as a good candidate to enable secure wireless communications in emerging wearable IoT devices that are subject to size and energy-constraints.
