Proceedings ArticleDOI
Washing durability of embroidered polymer coated RFID tags
Mikko Toivonen,Karoliina Koski,Elham Moradi,A. A. Babar,Lauri Sydanheimo,Leena Ukkonen,Yahya Rahmat-Samii,Pasi Kallio +7 more
TL;DR: In this article, the effect of washing on an embroidered RFID tag with a polydimethylsiloxane (PDMS) polymer coating is investigated by measuring the realized gain of the antenna before and after each washing procedure.
Proceedings ArticleDOI
Effect of temperature variation on remote pressure readout in wirelessly powered intracranial pressure monitoring system
M. Waqas A. Khan,Muhammad Rizwan,Lauri Sydanheimo,Yahya Rahmat-Samii,Leena Ukkonen,Toni Bjorninen +5 more
TL;DR: This work focuses on assessing the impact of variable temperature on the pressure readout at an off-body unit through in-vitro experiments.
Proceedings ArticleDOI
Phase retrieval antenna diagnostics for bi-polar planar near-field antenna measurements
TL;DR: A phase retrieval algorithm for bi-polar planar near-field measurements has been proposed, implemented, and successfully demonstrated using measured bipolar near field data in this article, where the focus is turned to the antenna diagnostics problem.
Resilience to Probe-Positioning Errors in Planar
S.F. Razavi,Yahya Rahmat-Samii +1 more
TL;DR: In this paper, the authors investigated the effect of probe positioning errors on the phase distribution of the far-field near-field measurements of a number of different types of antennas with high, medium and low side lobes, and showed the robustness of the Iterative Fourier technique even at the presence of very high probe positioning error.
Journal ArticleDOI
Analysis of near-field Cassegrain reflector: plane wave versus element-by-element approach
TL;DR: In this article, a near field Cassegrain reflector (NFCR) is used to magnify a small phased array into a much larger aperture antenna for limited scan applications, and the diffraction pattern from the subreflector is calculated by the geometrical theory of diffraction (GTD).
