Impedance mismatch in a circuit results in energy being reflected back to the source, reducing the amount of power available to the load and possibly causing damage to the power source. Matching the ...

If you catch a grizzled old radio amateur propping up the bar in the small hours, you will probably receive the gravelly-voiced Wisdom of the Ancients on impedance matching, antenna tuners, and LC ...

The purpose of this article is to explain, in detail, the process involved in building and tuning a high-frequency (HF) RFID antenna, which would operate at 13.56 MHz. Some concepts will be explained ...

The need for what’s called antenna tuning—either by adjusting the antenna itself or via a matching circuit between power-amplifier output and the antenna—is almost as old as wireless itself. Even in ...

ADELPHI, Md. -- A new, miniature, low-frequency antenna with enhanced bandwidth will enable robust networking among compact, mobile robots in complex environments. In a collaborative effort between ...

Embedded antennas, also known as chip antennas, or SMD (surface mount design) antennas, are used in on-board devices, small trackers, remote monitoring, Femto/PICO base stations, point of sale ...
