Bat Wireless BF2.4FNX42X12B1L120 is a widely used wireless communication product that uses a flexible substrate that can be bent, folded, and installed on curved surfaces or in narrow spaces.Flexible substrates (such as polyimide) enable circuits to adapt to complex spatial layouts and are suitable for wearable devices, folding screen mobile phones, etc. The thickness is usually 0.1~0.3mm which reduces the weight of the device and improves portability. 2.4G FPC has high- frequency performance, flexibility

Core Characteristics

1. Exceptional Flexibility & Conformability: Constructed with flexible base materials, it can be bent, folded, or curved to fit irregular surfaces—such as the inner curves of smartphones, the contours of wearable devices (smartwatches, fitness bands), or the tight spaces inside IoT modules. It maintains stable performance even after repeated bending (typically supporting 10,000+ bending cycles under standard conditions).
2. Ultra-Thin & Space-Saving: With a typical thickness of 0.1mm to 0.3mm (far thinner than rigid PCB antennas), it occupies minimal space. This makes it a top choice for slim devices like smartphones, tablets, or portable medical monitors, where internal component layout is highly dense.
3. Lightweight & Low Profile: Weighing only a few grams , it adds negligible weight to the end product—critical for wearable electronics and lightweight IoT devices that prioritize portability.
4. High Integration & Customizability: It can be easily integrated with other FPC components (e.g., connectors, sensors) during manufacturing, reducing assembly steps and improving production efficiency. Additionally, its shape, size, and radiation pattern can be customized to match specific device designs (e.g., internal embedded antennas, edge-mounted antennas) and frequency requirements.
5. Stable Electrical Performance: The conductive layer (usually copper foil) ensures low signal loss and consistent impedance matching. It supports a wide range of wireless frequencies, including 2.4GHz (Wi-Fi, Bluetooth), 5GHz (Wi-Fi), GPS/GLONASS (1575.42MHz), LoRa (868MHz/915MHz), and cellular bands (4G LTE, 5G NR). Most FPC antennas also undergo environmental testing (temperature, humidity, vibration) to ensure reliable performance in harsh conditions.
