antennas for 8.2 MHz Tag detection - edaboard.com

Re: antennas for 8.2 MHz Tag detection

Your best bet would probably be a multi turn loop antenna tuned to resonance.

The loop could be made quite small, or surround an entire enclosed area, depending on your requirements.

Cheers, Tony.

Re: antennas for 8.2 MHz Tag detection

Thank you Tony,

Most of practical systems have rather large antennas. And area of detection - distance between the antennas...

History of Ferrite Applications - Fair Rite

One of the first applications of ferrite vividly demonstrates the immediate advantage gained through its use. In 1944 soft ferrite was developed by J.L. Snoek and permitted a quantum leap in the efficiency of� telephony filter coils. Lower losses and higher permeabilities over a period of 30 years have reduced the size of the typical filter coil to 0.6% of the volume of the earliest version!...

Radio-Frequency Identification (RFID) is a technology that uses radio-frequency electromagnetic fields to transfer information from a tag to RFID reader for identification purposes. The tags do not require battery power. They derive power from the electromagnetic field generated from the reader. Some tags are also available which have their own power source. When it comes to RFID project...
