Abstract: Slot antennas built into metallic body panels utilize the vehicle body itself as an antenna radiator. Building the slot antennas directly into the metallic body panels converts the vehicle body from functioning as an RF shield into an RF antenna, which significantly improves mobile communication reception for a wide range of RF communication devices. Different types of slot antennas may be included for different communication channels utilized by different types of devices. Multi-band slot antennas are configured to receive multiple bands within a larger frequency channel. Dual-polarity antennas are configured to receive signals propagating in a dual-polarity mode. Multiple slot components may be configured as multi-band, dual-polarity antennas. Each slot antenna may be passive (without an RF pickup) or active with an RF pickup and coaxial cable connecting the antenna to an electronic device, such as receiver or amplifier located inside or otherwise interconnected with the vehicle.

Abstract: In accordance with exemplary embodiments, a drive system is provided for an electric or hybrid electric vehicle that provides reduces electromagnetic emissions. The system includes, but is not limited to, an electric motor and a transmission having a collar for receiving a portion of a drive shaft. The collar has an inside diameter proportioned to an outside diameter of the drive shaft to cause capacitive coupling between the transmission and the drive shaft thereby reducing electromagnetic emissions along the drive shaft.

Abstract: Vehicular electrical systems are provided. The vehicular electrical systems include a source device including an electrical component, a load device, and a cable assembly interconnecting the source device and the load device. The cable assembly includes a conductive core electrically interconnecting the electrical component and the load device, a conductive shield surrounding and being electrically insulated from the conductive core, the conductive shield having a first portion and a second portion, and an insulating body positioned between the first and second portions of the conductive shield such that the first and second portions of the conductive shield are electrically separated.
