Special session 2: Wearable Antennas and Biomedical Circuits

Short Bio: 
Jiahao Zhang was born in Hubei, China, in 1990. He received the B.S. degree in communication engineering from Huazhong University of Science and Technology, Wuhan, China, in 2012, the second B.S. degree in psychology from Central China Normal University, Wuhan, China, also in 2012, and the Ph.D. degree in electrical engineering from Katholieke Universiteit Leuven, Leuven, Belgium, in 2019.
From 2017 to 2018, he was with Norwegian University of Science and Technology, Trondheim, Norway, as a Visiting Researcher. In April 2019, he joined Lund University, Lund, Sweden, as a Visiting Researcher. Since late 2019, he has been an Assistant Researcher with National Key Laboratory of Science and Technology on Vessel Integrated Power System, Naval University of Engineering. His current research interests include electromagnetic compatibility, wireless body area networks, metamaterials, antennas, massive MIMO, and wireless power transfer.

Title:  A Metamaterial Inspired Button Antenna for Wireless Power and Data Transfer

Abstract:
A novel metamaterial inspired button antenna topology is proposed, integrating two working modes to transfer power and data, respectively. An omni-directional radiation is obtained in the 3.5 GHz WiMAX band to support on-body communication, while a circular polarized broadside radiation is achieved in the 5 GHz WLAN band to harvest power. An Artificial Magnetic Conductor (AMC) metamaterial structure is used to achieve a low-profile design. A wide bandwidth and high efficiency are observed. All these features make the proposed antenna suitable for on-body data transmission and off-body energy harvesting. A prototype has been fabricated. The measurement results are in good agreement with the simulation results.
