With enhanced intelligence and connectivity, automotive telematics systems and infotainment applications are increasingly complex. Today’s vehicle telematics systems provide two-way communication that sends, receives and stores information. Telematics control units connect vehicles with the outside world, enabling high speed internet access and access to car manufacturers’ entertainment and service offerings. Real time traffic information, location based services and emergency call are examples of the latest in car digital living space.
With infotainment systems, drivers can talk hands-free with Bluetooth connectivity, receive GPS route guidance, watch movies or listen to music while driving - all at the same time. With all this complexity, designers are facing more challenges than ever to balance performance with reliability.
Rogers is an experienced supplier of high-frequency materials for telematics and infotainment antennas and embedded systems. Due to their excellent electrical and mechanical properties, our high-frequency laminate materials are the materials of choice for designers who create high performance comfort, safety and entertainment functions like emergency call, navigation, video or music streaming and satellite digital audio radio.
In state-of-the-art truck and automobile antenna technology, or “smart antennas,” the receiver (antenna) technology and signal processing (ECU with transceiver and tuner, and in some cases LNA’s) are combined in one package to improve reception quality and reduce or eliminate cabling. Rogers high frequency AD series® printed circuit board (PCB) laminates can enable roof antennas that operate at 2.3GHz and receive satellite radio, even in very dense residential areas. The specific frequency of the antenna application determines the selected high frequency laminate with a particular dielectric constant. Rogers AD Series laminates are available in a range from Dk 2.5 up to Dk 10.0.
Concealed antennas are located in mirror, bumper, fender and rear tail-light locations. The almost invisible design eases installation without compromising styling. Rogers low loss materials and low profile LoPro copper foils provide solutions for designers facing the challenges of concealing antennas.
Rogers mid-Dk range AD Series laminates are extensively used in telematics and wireless applications such as; M2M (machine-to-machine), V2V (Vehicle-to-vehicle) and V2I (vehicle-to-infrastructure), DSRC (dedicated short range communications) and interoperable antennas for heavy and medium trucks and automobiles.
The on-board units (OBU) in innovative automatic toll collection systems use the cellular network and global positioning system (GPS) networks to calculate tolls. High performance Rogers RO4000® series materials are used in OBUs which establish a fast and reliable connection.
