Abstract: A connector assembly that provides a proper impedance connection between a CPW antenna mounted on automotive glass to a FAKRA-type connector. The connector assembly includes a PCB having a top surface and a bottom surface and being adhered to the glass. Vias are provided through the PCB to make electrical contact between metallization planes on the top surface and the bottom surface of the PCB. Terminals that are part of the connector extend through some of the vias, where ground terminals provide mechanical stability and make electrical contact with the metallization planes on the bottom surface of the PCB and a signal terminal provides an electrical connection to the antenna radiating element. The PCB is adhered to a substrate on which the antenna is mounted so that the metallization planes and microstrip lines make electrical contact with a CPW feed structure that feeds the antenna.

Abstract: A method for reducing power consumption in a transceiver front-end circuit for a cellular radio. The transceiver circuit includes a receiver module having a delta-sigma modulator that converts analog receive signals to a representative digital signal in an interleaving process, where the delta-sigma modulator includes a low noise amplifier (LNA), an LC filter and a quantizer circuit. The LC filter is a multi-order filter and the quantizer circuit is an interleaving quantizer circuit that interleaves multiple groups of bits from the filter. The method includes selectively reducing the order of the LC filter in situations where a full dynamic range of the cellular radio is not required and reducing a bit resolution of the quantizer circuit so as to reduce the power requirements of the cellular radio.

Abstract: Technical solutions are described for facilitating intra-vehicle wireless communication among a plurality of electronic control units. An example method includes determining, by a first electronic control unit in a vehicle, a wait-time for a message, which is to be transmitted to a second electronic control unit in the vehicle via a wireless channel. The first electronic control unit executes a first availability-check, by determining availability of the wireless channel. In response to the first availability-check indicating that the wireless communication channel is available, the method includes delaying transmission of the message by the wait-time. The method also includes executing, by the first electronic control unit, after passage of the wait-time, a second availability-check. In response to the second availability-check indicating that the wireless communication channel is still available, the method includes transmitting the message for receipt by the second electronic control unit.
