With a specialized three-dimensional Yagi-Uda antenna on loan, [saveitforparts] listens in on some of these signals. Some of it is presumably encrypted military activity, but there’s also some ...

While some ways exist to reduce their impact such as lightning rods, these passive systems can only be deployed in select locations and cannot prevent the build-up of the charge that leads up to ...

Modern drone warfare is evolving fast. In high-threat environments like Ukraine, enemies increasingly use low-band frequencies, especially 350-1300 MHz, to evade conventional counter-drone systems.

Drone warfare has become increasingly sophisticated, especially in high-conflict zones. Now, a new wideband antenna from Danish company MyDefence is aiming to close critical gaps in ...

Abstract: A compact cylindrical-shaped flat dielectric lens (FDL) antenna, partially sandwiched within a parallel-plate waveguide (PPW), is presented. The design elegantly combines uniform FDL ...

Abstract: This letter proposes a wideband two-dimensional (2-D) switched beam antenna array with single/dual/quad-lobed switched beams for direction of arrival (DOA ...

Luckily, a lot of the big brands out there have started putting out some great pre-built PCs with a ton of solid configurations that are worth picking up. While you could potentially spend less ...

SPARK Microsystems SR1120 is the company’s second-generation ultra-wideband (UWB) wireless transceiver capable ... cost BoM with only a 32.768 kHz crystal and a high-efficiency PCB antenna required.

This one caught my eye the other day. It's from The Register, about building a minimum PC for writers. What is described as an "antisocial writing rig".
