A multiband compact flexible energy harvester which consists of a novel slotted broadband antenna and miniaturized rectifying circuit is proposed for the primary communication (GSM-900, GSM-1800) industrial/scientific/medical (ISM-2450, ISM-5800) band applications. It found that newly designed combines coplanar waveguide-based feed structure with symmetrical sickle groove to obtain best matching performance radiation performance. network based on cross-shaped bent short-cut wire maximize...
This article describes a high-efficiency harmonic suppression metasurface (HSMS) energy collector, which is insensitive to frequency, input power, and load. A method of integrating function into collection (MS) improve system conversion efficiency proposed. Integrated RF synthesis channels in HSMS diode power availability turn-on time.

A flexible nonsymmetrical metamaterial tag with high gain, efficiency, and wide readable angle range is proposed here, whose working band 900–930 MHz. We improved impedance match between tag's antenna chip to reduce the mismatch loss increase radiation efficiency of by loading border cross units top or bottom defaulted above below central folded dipole. Furthermore, in size 95 mm×57 mm×0.23 mm, it can realize 5 dBi realized 89.13%, 54 m reading distance when reader's effective isotropic...
