St. Louis, Mo.—Laird Technologies has enhanced RadioAnt with Activv, an FM antenna that is embedded directly into a handset to improve performance, minimize product size, ease installation and lower ...

In January 2012 I looked at the venerable T network for impedance matching in AM antenna systems. Now I’ll discuss the L and Pi networks, and look at their use in antenna systems. The L network is the ...

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 ...

Something that all radio amateurs encounter sooner or later is the subject of impedance matching. If you’d like to make sure all that power is transferred from your transmitter into the antenna and ...

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 ...
