NASA had a big—and little—problem. For a small satellite, the agency needed a tiny antenna, with very specific communication ...

In this article, I will cover various aspects of millimeter wave (mmW) beamforming and antenna technology with what I consider interesting and unique technical design examples. Beamforming networks ...

Antenna design is often referred to as a black art or witchcraft, even by those experienced in the space. To that end, [Janne] wondered—could years of honed skill be replaced by bruteforcing the ...

Antennas are mandatory for a product to connect via radio frequency. Obvious examples are cell phones, satellite communications, and even our garage-door openers. But the Internet of Things is ...

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 ...

Designing and optimizing an antenna is not an easy task. If you want to build an industrial IoT antenna, you can use a reference design as a starting point, but what can you change to optimize the ...

Isolation refers to keeping multiple antennas separate from one another to avoid interaction effects. In some devices—especially cell phones, where multiple antennas must be squeezed into a small ...
