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 ...

There are many ways to test HF antennas ranging from simulation to various antenna analyzers and bridges. However, nothing can replace simply using the antenna to see how it works. Just as — ...

The magnetic loop antenna is a familiar sight in radio amateur circles as a means to pack a high performance HF antenna into ...

[Avionics Today 09-17-2015] Cobham Aerospace Communications has developed a Wide Band High Frequency (HF) antenna capable of transmitting data at a rate 10 times higher than traditional HF antennas, ...

Heliospace built two different types of radar antennas for the Europa Clipper mission: two High Frequency (HF) antennas, which deploy to over 55 ft in length, and four smaller Very High Frequency (VHF ...

At present, portable receivers generally use ferrite rod antennas for LF and MF (below 2 MHz), and whip antennas for HF (up to 30 MHz). Each type has proved effective in its particular application.
