Two-dimensional MoS2-enabled flexible rectenna for Wi-Fi-band wireless energy harvesting.
Xu Zhang,Jesus Grajal,J. L. Vazquez-Roy,Ujwal Radhakrishna,Xiaoxue Wang,Winston Chern,Lin Zhou,Yuxuan Lin,Pin-Chun Shen,Xiang Ji,Xi Ling,Ahmad Zubair,Yuhao Zhang,Han Wang,Madan Dubey,Jing Kong,Mildred S. Dresselhaus,Tomas Palacios +17 more
TL;DR: This work fabricates a fully flexible and integrated rectenna that achieves wireless energy harvesting of electromagnetic radiation in the Wi-Fi band with zero external bias (battery-free) and provides a universal energy-harvesting building block that can be integrated with various flexible electronic systems.
Journal ArticleDOI
Planar Dual-Mode Horn Array With Corporate-Feed Network in Inverted Microstrip Gap Waveguide
TL;DR: In this article, a 4 × 4 planar dual-mode horn array with low loss corporate feed network realized by using an inverted microstrip gap waveguide is presented, where the diameters of the horn apertures are larger than two wavelengths to allow more space for the feed network and thereby lower conductive losses.
Journal ArticleDOI
Approximate analysis of short circuited ring patch antenna working at TM/sub 01/ mode
Vicente Gonzalez-Posadas,Daniel Segovia-Vargas,Eva Rajo-Iglesias,J. L. Vazquez-Roy,C. Martin-Pascual +4 more
TL;DR: In this article, a study of the short circuited ring patch antenna based on the cavity model is presented, with special attention paid to the fundamental mode in this geometry: the TM/sub 01/mode.
Journal ArticleDOI
Size Reduction of Mushroom-Type EBG Surfaces by Using Edge-Located Vias
TL;DR: In this article, the position of the metallic via of a mushroom from its center to its edge was shown to move towards lower frequencies, allowing an easy structure size reduction which is critical in many applications.
Journal ArticleDOI
Study and Design of a Differentially-Fed Tapered Slot Antenna Array
E. de Lera Acedo,E. Garcia,Vicente Gonzalez-Posadas,J. L. Vazquez-Roy,Rob Maaskant,D. Segovia +5 more
TL;DR: The results of a parametric study and design of an ultrawideband dual-polarized array of differentially-fed tapered slot antenna elements are presented and it is demonstrated that anomalies may occur in the differential-mode scan impedance.
