IPEX Connector RG1.37 Cable 868MHz 3dBi FPC Integrated Antenna

Differences between similar antennas

Product introduction

1. Ultra-thin & Flexible Design

With a mere 0.1mm thickness and FPC construction, the GL148 easily integrates into compact or curved enclosures without adding bulk. Perfect for space-constrained IoT devices.

2. Optimized 868MHz Performance

Specifically tuned for the 868MHz frequency band (Europe ISM), delivering a 3dBi gain and VSWR ≤2.0 for stable, long-range transmission in LoRa, Sigfox, and other LPWAN applications.

3. High Power Handling & Low Loss

Supports up to 50W input power and comes with your choice of RG1.13 or RG1.37 coaxial cable, minimizing signal loss while maintaining 50Ω impedance for efficient RF matching.

4. Reliable Environmental Durability

Ruggedized to operate in temperatures from -30℃ to 60℃ and humidity up to 95%, ensuring consistent performance indoors or outdoors across seasons.

5. Standard IPEX Connector

Pre-fitted with an IPEX (U.FL-compatible) connector for quick, solderless attachment to common wireless modules (e.g., LoRa, Zigbee, Bluetooth gateways). Reduces development time and assembly cost.

Application Scenarios

◆LoRaWAN Sensor Nodes – Smart agriculture, water meters, and environmental monitors requiring long-range 868MHz uplinks.

◆Smart Home Gateways – Built into home automation hubs for connecting door/window sensors, motion detectors, and smoke alarms.

◆Industrial IoT Devices – Asset trackers, vibration sensors, and machine health monitors in factories.

◆Wearable Electronics – Flexible antenna fits into smart bands or health patches where rigid PCBs cannot be used.

◆Outdoor Weather Stations – Withstands temperature swings and high humidity while providing reliable telemetry links.

FAQ

Q: What frequency bands does the GL148 support?

A: It is designed specifically for the 868MHz ISM band (e.g., European LoRa, Sigfox). Not suitable for 915MHz or 2.4GHz.

Q: Can I use this antenna with a 915MHz device?

A: No, the antenna is tuned for 868MHz. Using it at 915MHz will cause higher VSWR and poor efficiency. We offer other models for 915MHz – please contact us.

Q: What is the cable length?

A: Standard cable length is not specified in the datasheet; custom lengths are available with RG1.13 or RG1.37 coax. Please inquire for your requirement.

Q: Is this antenna adhesive-backed?

A: The FPC material is not pre-installed with adhesive, but you can use thin double-sided tape or acrylic adhesive for mounting in your enclosure.

Q: How do I solder or connect the antenna?

A: It comes with an IPEX connector – simply plug onto your module’s IPEX receptacle. No soldering needed. For direct soldering, please contact us for custom termination.

Q: What is the minimum bending radius for the FPC?

A: We recommend a bending radius >5mm to avoid damaging the copper traces. Repeated sharp folds may degrade performance.
