Diversity antenna

摘要

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.

1. An electronic component in a vehicle tire condition monitor system, the electronic component comprising:
a first antenna and a second antenna, the first antenna oriented at an angle between about 45° and about 135° with respect to the second antenna, both of the antennas being capable of receiving RF signals transmitted from a plurality of sensors associated and rotating with respective tires of the vehicle, the RF signals from each of the sensors representing a condition of the respective associated tire, and the angle of orientation of the first antenna with respect to the second antenna enabling at least one of the antennas to receive the RF signals from each of the sensors independent of a rotational position of the sensor; and a processor receiving the RF signals from at least one of the antennas.
