Abstract
An antenna structure for a TPMS (Tire pressure Monitoring System) transmitter is disclosed herein. A TPMS transmitter couples with a valve so that a spiral coil within the TPMS transmitter can be electrically connected to a conduct body of the valve to get a specific resonance frequency. Hence, the length of the antenna structure can be increased effectively and the efficacy can be raised.
