This antenna spins to orient a pattern of wires ... inch round-head wood screws and fender washers. Buy an impedance-matching transformer (IMT) to maximize signal transmission from channels ...

Without using any mathematical formulas, we just stated something relevant and obvious about antennas: they are matching elements that match the guided wave to the free-space wave. Why does this ...

A good-quality SO-239 socket for the feedline connection and a 100 pF high-voltage capacitor for better matching on the higher frequency bands completed the transformer. With luck, this antenna ...

In one study, a high gain, compact disc-cone antenna was realised through the integration of an innovative non-Foster matching circuit, combining a negative impedance converter, transformer ...

STMicroelectronics has released a set of antenna-matching companion chips for STM32WL33 wireless microcontrollers (MCUs) to ...

If there’s one thing that amateur radio operators are good at, it’s turning just about anything into an antenna. And hams have a long history of portable operations, too, where they drag a ...

The following is a book review of what started out in 1987 as a compilation of research done on wideband transformers for matching vertical antennas to 50 W transmission lines. The author, Jerry ...

Impedance matching to an antenna in a receiver or transmitter is an essential process. Some loads are constant; thus, a single fixed Z-matching circuit can be used. But in other applications ...
