摘要:
The present invention relates to a reception antenna structure of a tire pressure monitoring system. The reception antenna is implemented using a cable-type antenna connected to a receiver of the tire pressure monitoring system. The cable-type antenna enables a mounting position of the antenna to be freely changed and improves a reception rate for measured data about temperature and pressure of a tire, that is modulated into data in the UHF band and transmitted to the outside of the tire in a wireless manner by a transmitter. According to the present invention, the reception antenna of a tire pressure monitoring system is implemented using a radiating leakage coaxial cable so as to enable the position of the antenna to be freely changed, so that, when tire pressure data is measured by a temperature and pressure sensor included in the transmitter within the tire and then transmitted through a tire pressure monitoring transmitter in a wireless manner, the reception sensitivity for the measured data is improved, thus increasing the reliability of the data measured at the tire, and guaranteeing the stability of the tire on the basis of the reliability of the reception sensitivity for the measured data.
