    摘要: An automotive tire pressure monitor with diversity antenna system employs a RF transmitter within each wheel/tire assembly and a vehicle mounted receiver with multiple receiving antennas. A first, primary antenna is located adjacent one vehicle window and a secondary antenna is located adjacent another vehicle window opposite the primary antenna. Both antennas are coupled to a receiver via a switch. The receiver feeds a processor, which is encoded to select the optimal antenna/receiver configuration based upon absolute signal strength (signal to noise), signal quality (completeness of encoded data) or signal reception rate. The signal received from the optimized antenna/receiver configuration is processed and transmitted to the host vehicle for system intervention and or display to an operator.

    摘要: An antenna system for a vehicle including a front windshield glass and a rear windshield is disclosed. The antenna system comprises an antenna unit including a radiating element electromagnetically coupled to an excitation element. The radiating element is coupled to the front windshield glass, and the excitation element is positioned on a passenger compartment interior surface of the front windshield glass. The antenna system also comprises a high-gain antenna unit including first radiating elements, a second radiating element, a 90-degree phase shift circuit, and a low noise amplifier that is coupled to the phase shift circuit. The first radiating elements receive signals through the rear windshield glass. The antenna unit and the high-gain antenna unit may function in a diversity antenna configuration.

    摘要: An antenna unit is disclosed. The antenna unit includes a wire antenna element and a patch antenna element. The wire antenna element creates a null at low-elevation angles to provide directional antenna patterns in azimuth planes. Nulls of the terrestrial signal pattern are directed toward the passenger compartment of a vehicle to create a larger spatial region for reception of terrestrial signals.
