A very low-tech way to make field recordings. The process I was intending to follow was simple enough. Set up the antenna in the middle of the field, have it transmit some RF, and measure the signal ...

Rohde & Schwarz and Greenerwave have reached a breakthrough in ESA antenna testing in a recent joint measurement trial, ...

You have probably heard the statement about standing wave ratio: “I changed the length of the transmission line and reduced the SWR.” Or the opposite statement, “I changed the length of the ...

An antenna and an electromagnetic receiver were the only equipment needed, both small enough to fit inside a backpack.

Over the past few decades, the explosive proliferation of smartphones, Wi-Fi, and Internet-of-Things (IoT) devices has intensified the need for additional frequency resources. The traditionally used ...

The principle of this work is demonstrated by using a laser to levitated nanoparticles and make them carry an electric charge to become an antenna that receives an external electric field containing a ...

Two Bell Labs astronomers, Penzias and Wilson, investigated a persistent background noise in their radio telescope. Initially ...
