Short-wave listeners often are not able to, or allowed to, install a long-wire antenna or other large dimension antenna in or around the home. In such cases, the present active antenna, intended for ...

I love all about electronics, circuit diagrams and crazy projects that can help us achieve almost everything our mind can conceive. I created this website and I want to invite you to participate in ...

Active integrated antennas and oscillators represent a cutting‐edge convergence of microwave circuit design and antenna engineering. By integrating an active oscillator circuit with a radiating ...

The author is a consultant in Carterton, New Zealand. This follows up his December article “Tuned Bandpass Filter Is Solution to Backup STL.” Many years ago, the active whip antenna and the active ...

This circuit shows an active antenna that can be used for AM, FM, and shortwave (SW). On the shortwave band this active antenna is comparable to a 20 to 30 foot wire antenna. This circuit is designed ...

A new type of device—a hybrid antenna with electronics developed by electrical engineers at the Georgia Institute of Technology—puts several transmitters and receivers on the same IC chip or package, ...

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 ...
