Es as low as 50 C. In such temperatures, the authors were unable to find materials with such low resistivity. The joints may be stretched, bent and even creased with pretty low effect around the conductivity in the technique.Electronics 2021, ten,9 ofThat implies that the textiles with mounted chips may very well be washed in the washing machine in a protective bag without the need of any failure. As a washable technology, the made material is appropriate for joining in total textile systems for everyday use. Together with the use of frequent dispensing, stencil- or screenprinting methods, it is actually simple to implement, with comparatively small financial outlay.Author Contributions: J.S. and V.S. performed most experiments, electrical and mechanical measurements, final information evaluation and wrote the paper. D.J. prepared the substrates and make contact with pads. S.R. performed the washing tests. L.W. ready samples for SEM and SEM photographs. C.K. and M.v.K. helped designing the research. M.S.-R. and M.J. place forward some amendments. All authors have read and agreed for the published version of your manuscript. Funding: Study was partially financed by the Polish National Agency for Academic Exchange NAWA. Conflicts of Interest: The authors declare no conflict of interest.
electronicsArticleDesign of Low-Profile Single- and Dual-Band Antennas for IoT ApplicationsWazie M. Abdulkawi , Abdel Fattah A. Sheta, Ibrahim Elshafiey and Majeed A. AlkanhalDepartment of Electrical Engineering, King Saud University, Riyadh 11421, Saudi Arabia; [email protected] (A.F.A.S.); [email protected] (I.E.); [email protected] (M.A.A.) Correspondence: [email protected]: This paper presents novel D-Fructose-6-phosphate disodium salt Endogenous Metabolite low-cost single- and dual-band microstrip patch antennas. The proposed antennas are realized on a square microstrip patch etched symmetrically with four slots. The antenna is designed to possess low cost and reduced size to utilize in Internet of items (IoT) applications. The antennas present a reconfigurable architecture that permits operation in distinctive wireless communication bands. The proposed structure is usually adjusted to operate either in single band or in dual-band operation. Two prototypes are Tenidap Protocol implemented and evaluated. The first structure operates at a single resonance frequency (f 1 = two.four GHz); however, the second configuration performs at two resonance frequencies (f 1 = 2.four GHz and f 2 = two.eight GHz) inside the identical size. These antennas use a low-cost FR-4 dielectric substrate. The 2.4 GHz is allotted for the industrial, scientific, and healthcare (ISM) band, and also the 2.8 GHz is allocated to verify the concept and may be adjusted to meet the user’s needs. The measurement of your fabricated antennas closely matches the simulated outcomes.

Introduction Lately, technologies growth has been growing swiftly. Most issues in the world and human life is going to be impacted by the internet. As a result, the internet of points (IoT) received in depth consideration in observing and sensing applications [1,2]. The IoT consists of your observation area for sensing data, network region for transmitting data, and app.
