Mitsubishi Electric this week announced that it has developed a prototype of the world's smallest antenna for high-precision satellite-based positioning in four frequency bands used by the world's main satellite-positioning systems and positioning-augmentation services.
The highly compact antenna, which is expected to be installed in diverse vehicles and even drones, will accelerate high-precision satellite-based positioning for autonomous driving and many other applications.
The antenna’s two folded linear elements are wired three dimensionally and symmetrically on each of four molded-resin layers, which are perpendicular to the module’s horizontal surface. This unique design has resulted in the world’s smallest four-band antenna for the high-precision satellite-based positioning of diverse autonomous vehicles, including drones and small tractors as well as automobiles.
