Angle of Arrival Estimation Via Small IoT Devices: Miniaturized Arrays vs MIMO Antennas
Zandamela, Abel; Chiumento, Alessandro; Marchetti, Nicola; Narbudowicz, Adam (2022)This tutorial discusses the problem of Angle-of-Arrival (AoA) estimation from small Internet of Things (IoT) devices. It reviews the limitations and challenges of existing miniaturization strategies, which involve classical ... -
Compact MIMO Antenna for MUSIC-Based Angle of Arrival Estimation in Wrist-Worn Devices
Zandamela, Abel; Marchetti, Nicola; Narbudowicz, Adam (IEEE, 2022)In this work, we propose a compact Multiple-Input Multiple-Output (MIMO) antenna for wrist-worn devices. The design is capable of unidirectional beamsteering across the entire horizontal plane, a property that is exploited ... -
Digital pattern synthesis with a compact MIMO antenna of half-wavelength diameter
Zandamela, Abel Abdul; Narbudowicz, Adam (2021)The paper presents a compact multiport antenna, with beamforming capabilities and a realized gain of 4.31 dBi with the size of λ/2. The antenna allows digital beamforming with independent control over three parameters: ... -
Feasibility Study of an Industrial Moisture Content Sensor Based on Wheeler Cap
Pratoomma, Prakorn; Zandamela, Abel; Chalermwisutkul, Suramate; Narbudowicz, Adam (IEEE, 2021)The paper proposes a technique for sensing of moisture content of a waste paper block based on Wheeler Cap measurement method. The technique allows sufficient penetration into the sample due to relatively low frequencies ... -
On the Efficiency of Miniaturized 360° Beam-Scanning Antenna
Zandamela, Abel Abdul; Narbudowicz, Adam (IEEE, 2019)The efficiency and beam-scanning performance of a compact, beam reconfigurable antenna are presented. The proposed design provides a 360° reconfigurable bidirectional radiation pattern in the horizontal plane by using phase ...
