As the concepts of autonomous driving and smart cars continue to advance, people have come to expect higher levels of interactivity, intelligence, and connectivity from their vehicles. Today, most automakers and suppliers—including Bosch, Continental, Delphi, Magneti Marelli, Mitsubishi, Volkswagen, and FAW—routinely integrate GNSS positioning capabilities into vehicles alongside other signals such as radio, TV, Bluetooth, and Wi-Fi. The entire system relies on antennas to provide external gain and coverage, and the key challenge today is how to integrate these components in a compact, efficient, and cost-effective manner.
