PROJECT TITLE :

Field Analysis and Measurement of Antiparallel Resonant Loop for Wireless Charging

ABSTRACT:

Among electromagnetic compatibility issues, radiated emissions constitute one in every of the areas of highest concern as a result of wireless power and communications systems operate by emitting magnetic fields. During this letter, the radiated field of the antiparallel loop is theoretically analyzed and experimentally verified at distances in the close to- and way-field regions. A reduced magnetic field strength of roughly vi dB is obtained with the proposed antiparallel loop when put next to a standard loop at the measuring distance up to ten m. Furthermore, since portable devices with an NFC perform need the configuration of straightforward structures for wireless charging, the proposed design concept for antiparallel resonant loops offers considerable benefits as it suppresses the generation of electromagnetic interference noise.
