    • 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 ...

    • 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 ...

    • 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 ...

    • Spherical Modes Driven Directional Modulation with a Compact MIMO Antenna 

      Zandamela, Abel Abdul; Marchetti, Nicola (2023)
      In this letter, a compact beamsteering MIMO antenna is proposed for Directional Modulation (DM) applications. A generalization of the beamsteering principle is presented and by exploiting the antenna’s unidirectional ...
