Distracted by Design] loves gear from the 1980s, though some of it isn’t as useful as it used to be. He happened across a ...

Abstract: A dual-band reflection-type linear cross-polarization converter (PC) is proposed using the antenna array back loaded with radio frequency circuit scheme. The antenna array is used to receive ...

This is an RDA5807 based FM stereo radio module. This module is designed to replace old, low-voltage, analog FM stereo receiver modules. Like many digital receivers, this module also got auto scanning ...

This is the material for a graduate-level radio-frequency integrated circuit course, held at JKU under course number 336.023 ("VO Integrierte Hochfrequenz-Schaltungstechnik"). Follow this link to ...

Discover how to build a simple wireless power transfer system at home using readily available components like enameled copper wire, an LED, a 2N2222A transistor, and a 9V battery. This step-by-step ...

Abstract: A novel scheme for designing electromagnetic functional surfaces (EMFSs) is proposed in this article. Different from traditional frequency selective surface (FSS), this scheme uses the ...
