“…Further research on DM is presented in [11], where Ding and Fusco introduced an orthogonal vector approach for DM transmitter (Tx) synthesis; in [14], Ding and Fusco also introduced a new type of DM Tx based on retro-directive arrays, where the injected orthogonal interference is not dependent on the preselected secure direction. Other contributions in the field are presented, e.g., in [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], and [31]; phased arrays are used in [15]; switched antenna arrays are discussed in [16], [17], and [18]; multiuser MIMO DM systems are studied in [19], [21], and [23]; timemodulated arrays are investigated in [20] and [26]; hybrid MIMO phased arrays are studied for millimeter-wave communication systems in [25]; and dynamic multibeam DM using random changes of the artificial noise vector at the symbol rate is proposed in [22].…”

“…Moreover, the solution uses a stacked patch approach, and similarly to [27], such designs are challenging for smartwatch devices' packaging. The work in [29] proposes a DM method using a / 3 2 m switched dipole antenna; however, it is still too bulky for integration into smartwatch devices. Recently, in [30], we proposed a five-mode antenna ( .…”

his article studies the security aspects of data transmission in on-body Internet of Things (IoT) devices through the use of Directional Modulation (DM) from a smartwatch integrated antenna. DM is a beam steering-based Physical Layer Security (PLS) method used to transmit baseband constellations to known secure locations while simultaneously scrambling them in other directions. However, in the state of the art, DM is implemented using large arrays, which are outsized for many on-body IoT devices. To overcome this challenge, this study proposes multimodal ultrathin compact antennas suitable for integration into smartwatches. These antennas present advanced beam steering capabilities that allow the implementation of DM from a low-thickness structure of up to 0.57 mm or 1/100th of the wavelength at the center operating frequency. Two different DM implementations (simultaneous multiport transmission and an energy-efficient single-port transmission) are tested using a multilayer phantom. Overall, secure steerable transmissions are realized, and experimental verifications are carried out to validate the proposed concept. Ultimately, this article demonstrates the feasibility of applying new energyefficient and low-cost security techniques to enhance the privacy of resource-constrained IoT devices.

“…Moreover, the solution uses a stacked patch approach, and similarly to [27], such designs are challenging for smart watch devices' packaging. The work in [29] proposes a DM method using a 3λ/2 switched dipole antenna; however, it is still too bulky for integration in smart watch devices. Recently in [30], we proposed a five-mode antenna (0.65λ diameter and 0.19λ profile), capable of unique steerable DM transmissions without high side lobes.…”
