Vehicule oriented switched antenna system

摘要

An antenna system is provided having switched directional antennas (20A and 20B). The antenna system includes a first antenna (20A) for receiving signals within a first directional coverage zone (21A), and a second antenna (20B) for receiving signals within a second directional coverage zone (21B). According to one embodiment, the first and second antennas (20A and 20B) are located on a vehicle (10). The system has a device (24) to detect orientation of the vehicle (10). The system further includes a receiver (30) having control circuitry (36) for controlling selection of the signals received from the first and second antennas (20A and 20B) based on orientation of the vehicle (10), location of one or more sources (26 and 28), and antenna coverage zones (21A and 21B) for the first and second antennas (20A and 20B).
