Is plain old FR-4 (also known as “Glass Epoxy”) PCB material suitable for use in RF designs[1]? This question comes up time and again. Many say no, fewer say yes – who's right? As I have published ...

[Hans Rosenberg] knows a thing or two about RF PCB design and has provided a three-part four-part video demonstration of some solid rules of thumb. We will cover the first part here and leave the ...

The IoT has increased the demand for good radio frequency (RF) design practices from the mains, to wall outlet power, all the way to the antenna. With several IoT standards employed today, constraint ...

In the past two columns we have looked at the possible side effects of adding a shield to our PCBs. First we showed how to calculate the lowest frequency resonance, backed up with actual data that ...

Antennas are sensitive to their surroundings. Thus, when there’s an antenna on the PCB, the layout for the design should take the requirements of the antenna into account, as this can make a huge ...
