3D Beam-Steering MIMO Antenna for On-Body IoT Applications
Zandamela, Abel; Marchetti, Nicola; Ammann, Max J.; Narbudowicz, Adam (IEEE, 2023)In this article, a compact 3D beam-steering MIMO antenna operating at 5.75 GHz is proposed for on-body Internet of Things (IoT) applications. The planar antenna comprises a central patch and two concentric annular rings. ... -
Compact Beamforming Antennas for Directional Modulation in IoT
Narbudowicz, Adam; Zandamela, Abel (2023)The paper discuss a PHY-layer security technique known as Directional Modulation (DM) and its implementations with compact beamforming antennas. The motivation is to allow DM to operate from small and low-complexity IoT ... -
Compact MIMO Antennas for Localization and PHY layer Security in Wrist Worn IoT Devices
Zandamela, Abel Abdul; Marchetti, Nicola; Ammann, Max J.; Narbudowicz, Adam (SFI, 2022)On-body IoT technologies, like wrist-worn devices, are becoming a key enabler of many cutting-edge applications such as connected healthcare systems (e.g, patient monitoring, in-hospital localization, sports fitness, and ... -
Directional Modulation for Enhanced Privacy in Smart Watch Devices
Zandamela, Abel Abdul; Marchetti, Nicola; Narbudowicz, Adam (2023)This article studies security aspects of data transmission in on-body Internet of Things (IoT) devices through the use of Directional Modulation (DM) from a smart watch integrated antenna. DM is a beamsteering-based Physical ... -
Non-Contact Radio Frequency Level Sensor Based on Wheeler Cap
Pratoomma, Prakorn; Zandamela, Abel; Narbudowicz, Adam; Chalermwisutkul, Suramate (2023)In this paper, we propose a novel non-contact liquid level sensor based on the Wheeler cap. The sensor utilizes an electrically small antenna operating at 276 MHz enclosed within a metal cap, in conjunction with the liquid ... -
Pattern and Polarization Diversity Multi-Sector Annular Antenna for IoT Applications
Zandamela, Abel; Marchetti, Nicola; Ammann, Max J.; Narbudowicz, Adam (IEEE, 2023)This work proposes a small pattern and polarization diversity multi-sector annular antenna with electrical size and profile of ka = 1.2lambda and 0.018lambda, respectively. The antenna is planar and comprises annular sectors ... -
Small Dual-Band 3D Beamforming MIMO Antenna
Zandamela, Abel Abdul; Marchetti, Nicola; Narbudowicz, Adam (IEEE, 2023)This work proposes a small dual-band (2.4 GHz and 4.89 GHz bands) 3D beamforming Multiple-Input Multiple-Output (MIMO) antenna for emerging size-constrained Internet of Things (IoT) applications. The performance is realized ...
