ANTENNA DEVICE HAVING ELECTROSTATIC DISCHARGE PROTECTION FUNCTION

摘要

PURPOSE: An antenna device having an electrostatic protection function is provided to reduce the number of transformers and to improve radiation property in order to have the band pass filter property. CONSTITUTION: An antenna device having an electrostatic protection function includes an antenna(20), an internal circuit(30), and an ESD protecting circuit(10). The internal circuit performs impedance matching with an antenna and processes a wireless signal through the antenna. The ESD protection circuit includes a transformer having band pass filter property.
