Non-Contact Radio Frequency Level Sensor Based on Wheeler Cap
(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
(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
(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 ...
