Applications of Transparent Antenna

Transparent antennae can be applied to diverse objects in our everyday environment, such as building windows, streetlights, bus stop walls, signs, and wearable devices.

Antenna

AoD (Antenna on Display), which consists of a transparent antenna mounted on a display, enables dual polarization in the three most commonly used mmWave 5G spectra worldwide.

Transparent Antenna

DONGWOO FINE-CHEM's AoD is an invisible antenna that is manufactured with the company’s proprietary processing technology into a metal pattern with a thickness about 1/100th that of a human hair. AoD technology ensures excellent antenna performance while maintaining high-definition display quality.

Triple-Band & Dual Polarization Antenna for mmWave 5G

Consisting of a transparent antenna mounted on a display, AoD is the world’s first innovative antenna technology to achieve dual polarization across three bands (n257, n258, and n260) of mmWave 5G networks.

360-Degree of Coverage for mmWave 5G

Smartphones that support mmWave 5G networks have an AiP (Antenna in Package) built into their side or back. AoD complements the existing AiP to achieve the 360° coverage required for seamless mmWave 5G communications.

Antenna

AoD technology can be implemented in various ways on smartphones and mobile devices that require high-speed communication. The invisibly thin and transparent antenna delivers excellent performance and can be mounted on a device without compromising its aesthetics wherever high-speed communication is required.

DONGWOO FINE-CHEM's transparent antenna is applicable to a wide range of frequency bands, such as LTE, 5G, WiFi6, and UWB, and can be implemented in various ways in places or devices that require high-speed communication, providing convenience in our daily lives.

FSS (Frequency Selective Surface)

FSS is a type of radio wave-controlling lens that improves 5G coverage by selectively reflecting or penetrating 5G radio waves.
FSS can be installed on the window glass of a car or building, enhancing the communication quality of 5G services.
