868MHz IPEX Connector Flexible PCB Antenna for IoT Devices

Product Introduction

Optimized for IoT: Precisely tuned to the 868MHz ISM band, designed specifically for Low Power Wide Area Network (LPWAN) and IoT wireless communication standards such as LoRa, Sigfox, and Zigbee, ensuring efficient signal transmission and reception.

Ultra-thin and Flexible Design: Utilizing flexible printed circuit board (FPC) material, its extremely thin profile allows it to bend and fit within curved surfaces or irregular spaces, providing significant layout flexibility for compact product designs.

Superior Electrical Performance: Voltage Standing Wave Ratio (VSWR) ≤1.5, indicating extremely high antenna-feeder matching, effectively reducing signal reflection and energy loss, and improving radiation efficiency and communication reliability.

Flexible Connectivity Options: Offers both standard IPEX connectors (cable connection) and direct soldering interface options, allowing for flexible selection of the most suitable integration method based on production line processes, cost, and reliability requirements.

Rugged and Durable: Despite its slim profile, the robust structure can withstand the operational stresses of routine assembly processes. Maximum input power of 20W meets the transmit power requirements of most IoT devices, ensuring consistently stable performance.

FAQ

Q: Does this antenna support frequency bands other than 868MHz?

A: No. The GLFPC041 is a single-frequency antenna designed and optimized for the 868MHz band (mainly used in Europe). For other frequency bands (such as 433MHz, 915MHz), please see our other product models.

Q: Which is better, IPEX connection or soldering?

A: It depends on production requirements. IPEX connection facilitates assembly and maintenance, making it suitable for mass production; direct soldering provides a stronger connection and is less expensive, suitable for designs with extremely tight space or extremely high connection reliability requirements.

Q: Is a clearance area required during installation?

A: Yes. To ensure optimal performance, it is recommended to reserve sufficient clearance area around the antenna radiator (especially above the ground plane) (refer to detailed design guidelines for specific dimensions) and avoid tight obstruction by metal parts or batteries.

Q: With a gain of only 3dBi, will the signal be weak?

A: 3dBi is a typical and practical gain value for this type of small omnidirectional antenna. It balances coverage and size. For the communication distance of most IoT devices (hundreds of meters to several kilometers), with a suitable RF front-end, the performance is perfectly adequate.

Q: What is the antenna's directivity?

A: It is an omnidirectional antenna, meaning it can radiate signals uniformly in 360 degrees on a horizontal plane, making it ideal for applications where the device orientation is uncertain.

Q: What is the operating temperature range? 

A: Standard commercial-grade FPC antennas typically support operating temperatures from -20°C to +70°C. For more stringent industrial or automotive-grade temperature requirements, please consult us in advance.
