In this paper, a 5.8 GHz, high-gain flexible receiving antenna (FRA) is proposed, which can be used for wireless power transmission (WPT) systems. The FRA designed by an iterative process and etched on Kapton, with coplanar waveguide (CPW) feed. order to improve the gain of FRA, air-gap reflector are loaded, improved from 2.79 9.51 dBi at GHz. To validate stability fabricated prototype uses thr...

Pulse-receiving characteristics such as bandwidth, sensitivity, and fidelity of several V-dipole antennas loaded with a nonreflecting resistance profile are analyzed, taking into account the effect of parameters such as the linear resistance at the feed point, the interior angle of the V-antenna, and the terminal resistance load.

A Doppler lidar system for wind velocity and direction measurement is presented. The lidar use a wide field of view (FOV) objective lens as an optical antenna for both beam transmitting and signal receiving. By four fibers coupled on different position on the focal plane, the lidar can implement wind vector measurement without any scanning movement.

Multilayer films consisting of Eu(OH)(3-x) and titanium oxide nanosheets showed strong Eu(3+) emission under UV-light irradiation, in which the titanium oxide nanosheet works as an antenna collecting UV-light, and then the Eu(OH)(3-x) nanosheet acts as an emitting layer receiving the absorbed energy.

Radio Frequency Identification is a technology where data is transmitted via radio waves on the electromagnetic spectrum. An RFID system consists of a radio frequency transceiver which both transmits and receives signals, and a miniature transponder in the form of an RFID “tag” that houses an antenna for receiving signals and a tiny chip containing the RF circuitry and the information to be tra...
