Abstract: A smart antenna system (32) and a method for the same for tire pressure monitoring are provided. The smart antenna system (32) comprises a plurality of antennas (212A˜212E). The smart antenna system (32) transmits respectively a test signal to a vehicle controller (10) via a plurality of antenna. The vehicle controller (10) selects the antenna transmitting test signals with highest received signal strength indication (RSSI) among the plurality of antennas (212A˜212E) as a default antenna. The tire pressure monitoring module (20) selects the default antenna as the antenna to send a tire pressure data signal.
