FAQ

Q: Does this antenna support other ISM bands such as 868MHz or 915MHz?

A: No. The GLFPC068 is a single-band antenna specifically designed and optimized for the 433MHz band. If you require other bands, please refer to our other corresponding FPC models.

Q: Should I choose IPEX connection or direct soldering?

A: IPEX connections facilitate production assembly, testing, and subsequent maintenance, making them suitable for mass production. Direct soldering offers a more robust physical connection and lower cost, suitable for designs with extremely limited space or high connection strength requirements. Please choose according to your production process and needs.

Q: What are the key considerations when mounting on the PCB?

A: The most critical is ensuring sufficient clearance. Clearance must be strictly adhered to design requirements on all PCB layers (especially the ground plane) within the antenna radiator projection area, and the area around the antenna must be kept away from large metal components or batteries; otherwise, performance will be severely degraded.

Q: Is a 3dBi gain sufficient for long-distance communication?

A: For the 433MHz band and this type of small omnidirectional antenna, 3dBi is a typical and practical gain value. Communication distance depends on the overall system link budget. With appropriate transmit power and receive sensitivity, it can meet the short-to-medium range communication needs of most IoT and remote control applications.

Q: What is the radiation pattern of this antenna?

A: It's an omnidirectional antenna, capable of 360-degree uniform radiation on a horizontal plane, making it ideal for applications where the device's orientation is not fixed or requires communication in all directions.

Q: What is its operating temperature range?

A: The standard commercial-grade FPC antenna typically operates from -20°C to +70°C. If you have more extreme industrial or automotive-grade temperature requirements, please specify this when selecting a model.
