Flexible LTE wideband antenna for wearable devices

　　Flexible LTE Wideband Antenna: Seamless Connectivity for Wearable Devices

　　Redefine connectivity for your wearable devices with our Flexible LTE Wideband Antenna—engineered to bend, conform, and integrate effortlessly into the sleek, dynamic designs of smart wearables. Tailored for wearable device manufacturers, health tech developers, and smart lifestyle solution providers, this antenna ensures stable LTE signal transmission for smart watches, fitness trackers, health monitoring patches, and smart clothing—all while preserving comfort, portability, and device aesthetics.

　　Core Advantages for Wearable Scenarios

　　1. Ultra-Flexible Design, Perfect Conformity

　　Crafted from high-performance flexible FPC (Flexible Printed Circuit) material, this antenna can withstand repeated bending (up to 10,000 cycles at a 5mm bending radius) without signal degradation—ideal for curved surfaces like smart watch straps, fitness tracker bands, or soft smart clothing. It conforms to the contours of the human body or device casing, eliminating the bulk of rigid antennas and ensuring zero impact on wearing comfort. Whether users are running, bending their wrists, or moving freely, the antenna maintains its shape and performance, adapting to daily dynamic use.

　　2. Ultra-Thin & Lightweight, Space-Saving Integration

　　With a thickness of just 0.15mm and weight under 0.5g, it occupies minimal space inside wearable devices—critical for the compact designs of smart wearables. It fits seamlessly into narrow gaps (e.g., between a watch’s display and battery) or can be embedded directly into soft components (like the fabric of smart fitness vests), avoiding bulky protrusions that compromise device sleekness. Its miniaturized size also reduces overall device weight, keeping wearables light enough for all-day use (e.g., a smart band with this antenna adds less than 0.3g to total weight).

　　3. Skin-Friendly & Durable for Daily Wear

　　Made with biocompatible materials certified to ISO 10993 standards, it is non-irritating to human skin—safe for direct, long-term contact (e.g., health monitoring patches worn on the arm or chest). The antenna’s surface is coated with a sweat-resistant, anti-friction layer that resists corrosion from sweat, lotions, or water splashes (IP64 防护等级), ensuring durability through daily activities like workouts, handwashing, or rainy commutes. It operates stably in a temperature range of -10℃ to +60℃, matching the typical environment of wearable use (from cold outdoor runs to warm indoor workouts).

　　4. Low Power Consumption, Extended Wearable Battery Life

　　Optimized for the low-power needs of wearables (which rely on small, rechargeable batteries), the antenna features a ultra-low power design (≤0.3W during active transmission). It reduces energy draw from the device’s battery, extending standby time by up to 35% compared to standard rigid antennas—critical for devices like fitness trackers or health monitors that need to run continuously for days. Its efficient signal capture also minimizes the need for repeated data transmission retries, further cutting power usage without sacrificing connectivity.

　　5. Stable Signal, Even in Dynamic Use

　　Covers all mainstream LTE frequency bands (700MHz–2700MHz, including Bands 1/2/3/4/5/7/8/12/13/17/20/28) for global compatibility, ensuring stable signal reception whether users are indoors (e.g., offices, homes) or outdoors (e.g., parks, running trails). With a low VSWR (≤1.5) and anti-interference technology (resistant to signal disruption from nearby electronics or body tissue), it maintains reliable data transmission—even during high-movement activities like jogging or cycling. This ensures real-time delivery of critical data, such as heart rate readings, GPS location, or fitness metrics, to cloud platforms or paired smartphones.

　　Key Technical Specifications

　　This flexible LTE antenna operates within the 700MHz–2700MHz frequency range, supporting global LTE networks to ensure compatibility with wearables sold in Europe, the Americas, Asia, and beyond. It delivers a gain of 2.5–3.5dBi (optimized for balanced signal strength and power efficiency) and features dual-linear polarization (±45°) to reduce multi-path interference from body movement or surrounding objects. It supports a maximum input power of 20W, matching the transmit power of most wearable LTE modules, and is equipped with a mini U.FL connector (or custom micro-connectors upon request) for easy integration into small device PCBs. Its flexible FPC base material offers a operating temperature range of -10℃ to +60℃, a bending radius as small as 5mm, and a bending life of over 10,000 cycles—all while complying with RoHS and REACH environmental standards.

　　Ideal Application Scenarios

　　Smart Watches & Fitness Trackers: Embedded into watch straps or device casings, enabling LTE connectivity for call-making, message receiving, and real-time fitness data sync (e.g., step count, calorie burn) without relying on paired smartphones.

　　Health Monitoring Patches: Conforms to skin surfaces to power LTE transmission of vital signs (e.g., heart rate, blood oxygen, ECG data) for remote patient monitoring—ideal for elderly users or chronic disease management.

　　Smart Clothing: Integrated into fabric layers of fitness vests or sports leggings, supporting LTE-connected biometric tracking (e.g., muscle activity, body temperature) for athletes during training.

　　Kids’ & Elders’ Safety Wearables: Built into lightweight 定位手环，ensuring stable LTE signal for real-time location sharing and emergency call functions—even when kids play outdoors or elders go for walks.

　　Smart Glasses: Bent to fit the frame of smart glasses, enabling LTE connectivity for hands-free navigation, video calls, or work-related data access (e.g., for field service technicians).
