Advantages

• Ultra-Thin and Lightweight “No Burden”: The ultra-thin size of 16×6×4.5mm + ultra-light weight of 2.33g is the key for smart wearables and micro devices to achieve “invisible integration”, which neither affects the appearance design of the device nor increases the carrying burden.
• Strong and Stable Signal Reception: The combination of RHCP and high-gain LNA far exceeds ordinary antennas in terms of positioning speed and accuracy in urban canyons, indoor weak signal scenarios, providing stable signal support for devices.
• Ultra-Flexible Integration: Customizable connection solutions + press-fit installation can adapt to the structural limitations of different forms of devices such as smart bracelets and micro sensors, helping to innovatively integrate product functions and forms.
• Ultra-Reliable Quality: Ceramic material has strong weather resistance, and the wide temperature range design + RoHS compliance not only ensures the stable operation of devices in long-term outdoor and industrial environments but also meets the environmental quality requirements of consumer electronics.

Application Scenarios

• Smart Wearables: Integrated into smartwatches and health bracelets, providing real-time and precise positioning in outdoor scenarios such as running and mountain climbing. The ultra-thin design does not affect the wearing comfort of the device, achieving a perfect combination of “fashion and function”.
• Micro IoT Trackers: Such as micro pet trackers and jewelry positioning tags, the ultra-small size + low-power characteristics make it possible to “invisibly” embed in tracked objects, realizing precise traceability in home and logistics scenarios without affecting the appearance and use of tracked objects.
• Medical Micro Devices: Such as wearable health monitoring devices (smart patches), the ultra-thin and lightweight design can fit human skin, providing precise positioning while monitoring health data, helping to intelligentize management in medical scenarios.
• Consumer-Level Micro Drones: Equipped on mini aerial photography drones (such as pocket drones), the high-gain antenna ensures precise navigation in complex terrains (such as urban buildings), enabling stable aerial photography and path planning, and the overall device remains extremely portable.
• Industrial Micro Sensors: In micro monitoring nodes of industrial automated production lines, the wide temperature range and high reliability ensure stable transmission of position data in high-temperature, cold storage and other environments, helping to refine the upgrading of intelligent manufacturing.
