There’s a joke in the world of radio that all you need for a HF antenna is a piece of wet string, but the truth is that rudimentary antennas rarely perform well. Random pieces of wire may pull in some ...

Phased array antenna systems are at the cusp of ubiquity. We now see Multiple-Input Multiple-Output (MIMO) antenna systems on WiFi routers. Soon phased array weather radar systems will help to predict ...

Ken Beckwith is a field engineer with EMF based in Nebraska. Being a hands-on engineer, Ken has done his share of construction over the years. One of his projects was the construction of an ...

POLARIZATION. We use the word in everyday speech to mean a division into two groups with sharply contrasting opinions or beliefs. But the word has another use in physics and electrical engineering to ...

Last month I wrote some about making a notch filter for the AM band. However, before you have any signals to notch out, you must first, of course, have some signal to begin with. Let’s talk a little ...

SpaceX is developing lighter and cheaper phased array antennas to receive internet from low-earth orbit satellites. Low-Earth Orbit satellites will be will need to have fast tracking from receivers as ...

To deliver the next generation of satellite applications, spacecraft are increasingly using phased arrays to combine multiple individual antenna elements to improve overall performance, increase gain, ...

Evolving communication systems are driving developments in the RF/microwave industry. The large umbrella of 5G focuses on supporting three main technologies: enhanced mobile broadband, which is the ...
