Abstract:
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.
