Ultra-Thin Ceramic Antenna for Wearable Electronics

　　Ultra-Thin Ceramic Antennas: Space-Saving Signal Solutions for Wearable Electronics

　　In the wearable electronics industry, "slim form factor," "wearable comfort," and "stable connection" are crucial, and our ultra-thin ceramic antennas redefine what's possible in compact devices. Leveraging advanced thin-film ceramic technology and optimized RF design, they address key pain points of traditional antennas (e.g., bulky design constraints, signal loss due to skin contact, and high power consumption), while also meeting the diverse needs of smart wearables, from fitness trackers to medical monitors.

　　Core Technology Features: Designed for Superior Wearables

　　1. Extremely Thin: Maximizing Design Freedom

　　Unparalleled Thinness: With a thickness as low as 0.6 mm (customizable down to 0.4 mm for ultra-thin devices), this antenna is 60% thinner than traditional ceramic antennas (typically over 1.5 mm thick). It seamlessly fits into wearable device cases with a total thickness of 5 mm or less (e.g., slim smart bracelets, lightweight smart glasses).

　　Ultralight: Weighing ≤ 0.15g, less than 0.5% of a standard smart bracelet (approximately 30g), this eliminates complaints of bulkiness or heaviness, ensuring all-day wear comfort—even for delicate devices like children's wearables or medical patches.

　　Space-Saving Design: Occupies 45% less PCB area (e.g., 8mm × 5mm × 0.6mm, compared to 10mm × 6mm × 1.2mm for conventional models), freeing up space for larger batteries or additional sensors (e.g., heart rate monitors, blood oxygen sensors) in compact wearable devices.

　　2. Multi-Band Compatibility: Meets all wearable device functional requirements

　　Single-Stop Support for Multiple Key Wearable Use Cases:

　　Bluetooth 5.3/Bluetooth LE (2.402-2.484GHz): Supports low-power data synchronization (e.g., syncing fitness data to a smartphone) and wireless calls (e.g., connecting to a smartwatch), with a range of up to 100 meters (in open areas).

　　GNSS (GPS L1: 1575.42MHz; GLONASS G3: 1602MHz): Supports precise outdoor positioning (≤2.5m accuracy), making it ideal for running, hiking, or tracking children's locations—critical for sports- and safety-focused wearables.

　　NFC (13.56MHz): Optional integration for contactless payments (e.g., tap-to-pay for smartwatches) or device pairing, eliminating the need for a separate NFC antenna.

　　LTE-M/NB-IoT (1.8GHz/2.1GHz): Ideal for medical wearables (e.g., remote heart rate monitors) that require long-range, low-power cellular connectivity for real-time data transmission to cloud platforms.

　　3. Ultra-Low Power Consumption: Extends wearable battery life.

　　Minimum operating current: As low as 2.8mA (Bluetooth LE mode) and 4.5mA (GNSS mode), 35% lower than standard ceramic antennas. Reduces antenna power consumption in wearable devices by 20%, extending standby time by 6-10 hours (based on a 200mAh smart wristband battery).

　　Power Saving Mode: Automatically adjusts power output based on signal strength (e.g., reducing to ≤1.5mA in a stable Bluetooth environment), avoiding unnecessary energy waste during daily use (e.g., indoor activity tracking with a smart wristband).

　　4. Human Body Interference Resistance: Stable signal even with skin contact

　　Special Dielectric Material: Utilizes modified alumina ceramic (εr = 7.8 ± 0.2, tanδ ≤ 0.0006 at 2.4GHz) with low skin effect sensitivity, minimizing signal attenuation caused by direct contact with human skin or clothing.

　　Isolation Layer Design: An ultra-thin 0.1mm electromagnetic isolation layer is integrated between the antenna and the device PCB, reducing signal loss caused by human body capacitance by ≤8% (compared to 15-20% for traditional antennas). This ensures stable connectivity even when the device is worn snugly (e.g., no Bluetooth connection drops during exercise).

　　5. Robust Environmental Adaptability: Designed for Everyday Wear and Sports

　　IP68 Water and Sweat Resistance: Featuring a nano-hydrophobic coating, it withstands immersion in 2 meters of water for 30 minutes (suitable for swim wearables) and passes a 72-hour sweat corrosion test (per ISO 10289 salt spray standard), making it ideal for fitness trackers and sports watches.

　　Flexibility and Durability: Supports over 1,000 bending cycles (1 mm radius, 90° angle) without compromising performance, making it compatible with flexible wearable devices such as smart wristbands and skin patches.

　　Wide Temperature Range: Reliably operates from -25°C (for cold outdoor running) to +70°C (for hot weather use) without signal drift or power spikes.

　　6. Easy Integration and Global Compliance

　　SMD (Surface Mount Device) Package: Compatible with standard wearable PCB assembly lines (reflow temperature: 260°C ± 5°C), eliminating the need for external mounting brackets. It can reduce assembly time by 25% and lower production costs for manufacturers.

　　Global Certifications: Compliant with FCC (US), CE (EU), TELEC (Japan), SRRC (China), and ISO 13485 (medical wearables) standards—simplifying your product's entry into global markets, including the stringent medical device market.

　　Applications: Suitable for all wearable device types.

　　Smart Bracelets/Fitness Trackers: Ultra-thin design fits into slim housings; low power consumption enables 24/7 activity tracking.ps, calories) and Bluetooth sync.

　　Smart Glasses: Compact size (e.g., 6mm×4mm×0.5mm) fits frame temples; stable Bluetooth/LTE connectivity enables hands-free calls and navigation.

　　Medical Wearables (e.g., Heart Rate Monitors, Glucose Sensors): Anti-interference design ensures accurate data transmission; ISO 13485 compliance meets medical device requirements.

　　Kids’ Smart Watches: Lightweight (≤0.12g) and durable; GNSS/Bluetooth support real-time location sharing and parent-kid calls.

　　Smart Jewelry (e.g., Smart Rings): Ultra-mini size (5mm×3mm×0.4mm) fits jewelry designs; NFC support enables tap-to-pay and device pairing.
