The author Gertrude Stein once said: “A rose is a rose, is a rose is a rose.” Maybe “An antenna is an antenna, is an antenna” also applies, but an AM antenna is an AM antenna is an FM antenna. Their ...

An antenna is an electrical component that is needed to transmit and receive electromagnetic energy from the space surrounding it in order to establish a wireless connection between two or more ...

There is no way to cover all the important concepts of directional antennas in a single column. There have been many voluminous tomes written about this subject. This month we will look at some of the ...

The field of antenna measurements has seen substantial advancements through the development of near-field to far-field (NF-FF) transformation techniques. These methods are vital for accurately ...

Measuring antenna gain patterns is a critical part of evaluating the performance characteristics of an antenna under test. A software-defined radio (SDR) is an economical and flexible radio system ...

Researchers continue to develop new antenna measurement methods, this time for future 5G wireless communications systems. Researchers at the National Institute of Standards and Technology (NIST) ...

Like a lot of people, [Bruce] likes radio controlled (RC) vehicles. In fact, many people get started in electronics motivated by their interest in RC. Maybe that’s why [Bruce] did a video about ...
