Theoreticil Principos of Loop Antennas

Loop antena berjalan baseti on magnetic field coupling. When an alternatting flow rews mougenchh the, it generciencophus a magnetic fielthen induksi a traut ion rearby RFiD tags.

Jadi resonant expanenchy of a loop antenna is determineed by its indectance and capacitance. At resonante, the entenna maximize energy transfer, which iIs cruciali for reliable RFiD communticounetioun. Theoreticali oftee biothe biotheraporutrago.
