Abstract
An electronic component in a vehicle tire condition monitor system includes a first antenna, a second antenna, and a processor. The first antenna is oriented at an angle with respect to the second antenna. Both of the antennas are capable of receiving RF signals transmitted from a sensor associated with a respective tire of the vehicle. The RF signals represent a condition of the respective tire. The processor receives the RF signals transmitted by the sensor from at least one of the antennas. The first and second antennas receive the condition signals from any of a plurality of the sensors associated with respective tires on the vehicle.
