When it comes to actual antennas in the real world, much of our knowledge is empirical. We know very broadly theories that explain how a point charge radiates (Maxwell’s equations), the need for ...

Placing an antenna in a design always needs care, but when there are two or more antennas in the design, it is even more important to understand how the antennas radiate, how they will perform ...

We may receive a commission on purchases made from links. A strong and reliable Wi-Fi signal has become a necessity for modern-day homes and businesses. As such, many of us are going to great lengths ...

Smartphones today are always fighting two big battles: keeping a strong signal and staying cool when things get tough. Most ...

We all want our test systems to have the smallest possible number of instruments and components. When you�re conducting EMC studies across a wide range of frequencies, from the low megahertz region ...

Antenna tuning at HF frequencies is something that radio amateurs learn as part of their licence exam, and then hone over their time operating. A few basic instruments and an LC network antenna tuner ...

Ideally, EMC testing could be accomplished with one antenna, one amplifier, and one receiver. At least the receiver part generally can be achieved, and in some sports, one out of three is pretty good.

To use a smaller antenna, we need a higher signal frequency, and that’s what we do when we apply modulation to the signal. Modulation is simply encoding the low frequency signal in the information of ...
