Abstract
In this paper, the rectangular spiral shaped antenna is designed and fabricated for 433 MHz TPMS. Proposed antenna has the -10 dB impedance bandwidth of 23 MHz(427~450 MHz). The antenna is fabricated with the size of $5mm(W){\times}23mm(D){\times}10mm(H)$ by brass material. Return loss is below -10 dB at 433 MHz${\pm}$10 MHz mounted tire wheel and not mounted both. The radiation power is -44.21 dBm without wheel and -50.0 dBm installed wheel. The proposed antenna can be practical use through data transmission test results.
