In today's miniaturized world of IoT and connected devices, external antennas are often impractical. The 2.4-2.5 GHz FPC Internal Antenna offers the perfect solution, providing high-performance wireless connectivity in an ultra-slim, flexible, and easy-to-integrate form factor.
Specifically tuned for the critical 2.4 GHz ISM band (Wi-Fi 802.11b/g/n, Bluetooth, Zigbee), this antenna is designed for engineers and manufacturers who require reliable, hidden connectivity within tight device enclosures.
This assembly combines a thin, lightweight Flexible Printed Circuit (FPC) Antenna element with a micro-diameter 1.13 Coaxial Cable, terminated with the standard I-PEX/U.FL Connector. This standardized configuration ensures minimal space requirements and seamless integration with virtually all modern wireless modules and system-on-chips (SoCs). Optimize your product's aesthetics and functionality without compromising on signal quality.
Designed for Integration: Flexible Printed Circuit Technology
The core advantage of the FPC antenna is its construction. Utilizing flexible circuit board technology, this antenna offers a blend of high electrical performance and physical adaptability unmatched by traditional rigid antennas.
Ultra-Slim and Adaptable Form Factor
The thin, flexible nature of the FPC element allows it to be placed in locations where no other antenna can fit—curved surfaces, behind panels, or along the inside walls of compact enclosures.
Space-Saving: Extremely low profile minimizes the space taken up inside your device, freeing up crucial room for batteries, processing units, or other components.
Easy Installation: Typically includes an adhesive backing (model dependent), allowing for quick peel-and-stick mounting to the non-metallic interior surface of your product chassis.
High Performance: Despite its size, the antenna is carefully tuned to deliver effective gain and high radiation efficiency across the crucial 2.4-2.5 GHz range, guaranteeing robust wireless link quality.
The FPC design is the ideal choice for small consumer electronics, smart home devices, compact IoT sensors, handheld scanners, and medical devices where both aesthetics and internal space are premium concerns.
The Connectivity Standard: 1.13 Cable and I-PEX Connector
Signal delivery in miniaturized systems requires components that are both small and effective. This antenna is equipped with the industry-standard micro-coaxial assembly.
Micro-Diameter 1.13 Coaxial Cable
The 1.13 Coaxial Cable is specifically chosen for its ultra-fine diameter and flexibility, making it the perfect conduit for connecting the antenna element to the main PCB (Printed Circuit Board) in dense device environments.
Minimal Footprint: Its small size allows for easy routing through extremely tight spaces within the device enclosure.
Low Interference: Ensures effective signal shielding and low-loss transmission of the 2.4 GHz signal, maintaining the quality captured by the FPC element.
Universal I-PEX / U.FL Connector
The cable is terminated with the globally recognized I-PEX (often interchangeable with U.FL) connector. This is the de facto standard micro-coaxial connector for embedded wireless modules.
Broad Compatibility: Provides simple, secure snap-on connectivity to the mating receptacle found on virtually all Wi-Fi, Bluetooth, and IoT modules (e.g., ESP32, Raspberry Pi Compute Modules, NXP chips, etc.).
Secure Connection: The locking mechanism ensures a stable link resistant to vibration, which is critical for mobile or industrial IoT devices.
The combination of the FPC antenna, the flexible 1.13 cable, and the I-PEX connector represents the most commonly used, reliable, and compact internal antenna solution for high-volume product manufacturing.
Key Applications: Powering the Modern IoT Ecosystem
The 2.4-2.5 GHz FPC Internal Antenna is essential for a vast range of products that rely on Wi-Fi and Bluetooth for communication.
