Inspired by a dolphin’s ability to detect a wide range of frequencies, CIT Co. Ltd.’s Dolphin is a revolutionary Transparent Antenna with ultra-thin copper circuit technology. The innovative Dolphin supports the broadest range of frequencies among transparent antennas. CIT Co. Ltd., a leading startup in advanced materials, recently was awarded the CES 2025 Innovation Award in the Vehicle Tech & Advanced Mobility category for its revolutionary transparent antenna.
Unlike existing transparent antennas which are limited in frequency range and application, Dolphin’s design combines superior performance and flexibility. This is especially useful for autonomous driving technologies and the rise of Software Defined Vehicles (SDVs), often described as “smartphones on wheels.”
Dolphin is particularly adapted to 5G communication necessary for today’s modern connected vehicles:
Dolphin operates across six frequency bands, from L-band to K-band, and supports frequencies up to 20 GHz, making it uniquely suited for 5G communication. Its exceptional frequency coverage significantly surpasses that of conventional antennas, meeting the needs of modern connected vehicles.
When integrated into car windows or other glass surfaces, Dolphin’s remarkable design makes the antenna become nearly invisible. The Dolphin antenna achieves “an extraordinary 90% transparency using ultra-thin copper circuits less than 10 nanometers thick—1,000 times thinner than a human hair.” Other antennas copper circuits are 5 to 10 micrometers thick, more thicker than Dolphin’s thin and flexible design. Dolphin uses recycled copper wires for environmentally responsible production which helps reduce its carbon footprint to just 1/1000th of that of traditional antennas.
Besides Dolphin’s usage for automotive applications, incorporating it in smart building windows, streetlights, and bus stop glass panels, provides for applications in urban infrastructure. Other Dolphin applications include transparent displays:
Additionally, CIT’s advanced material technology has been applied to create transparent displays. These displays use ultra-thin copper circuits that are invisible to the human eye, delivering a clear and seamless viewing experience. Transparent displays are increasingly popular in digital signage, exhibition halls, commercial spaces, and transportation systems such as cars, buses, and trains.
