RF front ends are advancing through the integration of high-frequency passive networks with increasingly efficient active devices engineered for ultra-wide bandwidths and constrained power envelopes.

Abstract: In this paper, a measurement scheme, which eliminates the interference of the common mode current, for electrically small antennas is proposed. Firstly, the causes and effects of common mode ...

If you’re a regular reader of Hackaday, you may have noticed a certain fondness for Meshtastic devices, and the LoRa protocol ...

Abstract: Concept of ringed stacked patch antenna with low side lobe level and enhanced bandwidth is introduced for radio altimeter avionics applications. One dimensional electromagnetic band gap is ...

[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 cheap old FM radio with a great look, but wanted to repurpose it into ...
