The on-chip 330pF LC-tank capacitor is trimmed to +/- 3 percent which is unique in the market, with no other external component required than the antenna coil
It will power the tag only when the plane of the tag's antenna coil
is parallel with that of the reader's.
The antenna coil
is what transmits the signal, you don't need a battery" Michael McAlpine, the team's principal investigator, said.
Whatever the outcome of these full-body scanning evaluations, it is clear that the abdominal threat does not require the same magnitude of antenna coil
sizes or power as may be needed for other QR applications.
The sensors are comprised by a spiral induction (L) antenna coil
and a plate or interdigitated capacitor (C) that is in contact with the quantity to be measured.
The application-specific anntenna driver device provides unique performance which includes the full functionality to generate a magnetic LF field in conjunction with an antenna coil
to transmit data to a receiver in a key fob or card.
The closest they can get their antenna coil
to the prostate non-invasively is to place it under the buttocks.
The Atmel ATA5577M1330C-PP enhances the Atmel LF RFID portfolio with a stand-alone, fully functional tag that includes an antenna coil
trimmed to an operating frequency of 125kHz.
The ATA5505 makes building a complete reader an easy process requiring just a few external components and an antenna coil
26-28, at the Chicago Hilton and Towers in Chicago, where he will be presenting a paper on "Manufacturing and Reliability of Chip Module to Antenna Coil
Contacts in Dual Interface Smart Cards.
The two coil wires can directly be soldered onto the two pads of the package and mounted or glued onto the antenna coil
Embedded in these cards is a metallic antenna coil
, which allows them to communicate with an external antenna.
