Mitsubishi Electric Develops World’s Smallest Antenna Prototype for High-precision Satellite-based Positioning in Four Frequency Bands

Mitsubishi Electric 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 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.

The prototype’s L1 bandwidth, which is about triple that of the company’s existing model, is achieved with three-dimensional wiring and an antenna configuration optimized for space limitations. The new antenna supports major positioning-satellite systems and positioning-augmentation worldwide. Positioning precision is enhanced with the antenna’s unique structure, which combines both straight and loop elements to reduce back lobe radiation, thereby suppressing multipath waves reflected from the ground.
