A Liquid Metal‐Based Frequency Reconfigurable Patch Antenna With Cross Placed Fluidic Channel (2025)
Journal Article
Fang, X., Qu, Z., Alqurashi, K. Y., Kelly, J. R., & Alkaraki, S. (2025). A Liquid Metal‐Based Frequency Reconfigurable Patch Antenna With Cross Placed Fluidic Channel. Microwave and Optical Technology Letters, 67(2), Article e70112. https://doi.org/10.1002/mop.70112

In this letter, a novel frequency reconfigurable antenna with the aid of liquid metal is presented. The proposed antenna incorporates a 3D-printed fluidic channel, which is placed cross to the metallized part of radiator. Compared to general meandere...

Power Transmission for Millimeter-Wave Indoor/Outdoor Wearable IoT Devices Using Grounded Coplanar Waveguide-Fed On-Body Antenna (2025)
Journal Article
Erman, F., Koziel, S., Zyoud, A., Leifsson, L., Ullah, U., & Alkaraki, S. (2025). Power Transmission for Millimeter-Wave Indoor/Outdoor Wearable IoT Devices Using Grounded Coplanar Waveguide-Fed On-Body Antenna. IEEE Access, 13, https://doi.org/10.1109/ACCESS.2025.3528871

This paper presents for the first-time evaluation of wireless power transmission (WPT) for sustainable low-powered Internet of Things (IoT) devices in realistic indoor/outdoor scenarios using empirical propagation models at 28 GHz. The used empirical... Read More about Power Transmission for Millimeter-Wave Indoor/Outdoor Wearable IoT Devices Using Grounded Coplanar Waveguide-Fed On-Body Antenna.

A Microwave Subsystem (MS) Capable of Realizing Functional Change with the Aid of 2D-shaped Liquid Metal (LM) (2024)
Journal Article
Fang, X., Alkaraki, S., & Kelly, J. R. (2024). A Microwave Subsystem (MS) Capable of Realizing Functional Change with the Aid of 2D-shaped Liquid Metal (LM). Progress In Electromagnetics Research B, 108, 17-30. https://doi.org/10.2528/pierb24062303

This paper presents the first microwave subsystem (MS) capable of changing its function, in this case between resonator and antenna, using liquid metal (LM). This is achieved by filling/emptying fluidic channels with Gallium-based LM and forming LM i...
