Abstract: An antenna module for a vehicle communication system can be attached to a vehicle using an attachment arrangement that includes a cast and a single module that incorporates a bolt with an integrated retainer clip. The attachment arrangement acts as its own snap. The retainer clip has a spring mechanism. The installer installs the attachment arrangement to a through hole, for example, in a vehicle roof panel. As the retainer clip passes through the through hole, it collapses around the body of the cast. After the retainer clip passes completely through the through hole, the spring mechanism causes the retainer clip to rebound back to its original span to temporarily hold the antenna module in place. The installer then tightens the bolt, thereby stroking the integrated retainer clip up the cast toward the vehicle roof panel. When the retainer clip contacts the vehicle roof panel, the installer further tightens the bolt to a recommended drive torque.

Abstract: 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.

Abstract: An antenna module incorporates a microstrip patch antenna and a mast antenna in an at least substantially concentric arrangement for communicating signals in multiple communication bands. The output signals from the microstrip patch antenna and the mast antenna are output via a single RF cable. The antenna module can be used to communicate signals in multiple communication bands, including both satellite and terrestrial communications. The antenna module conserves space, while avoiding unacceptable distortion of radiation patterns for satellite services. In addition, the mast antenna can be implemented using a thinner, more flexible construction than certain conventional solutions. Further, providing the outputs from the antennas via a single RF cable may facilitate collocating tuners for multiple communication services, resulting in considerable size and cost savings by using a single set of RF cables and connectors.
