FAQ

Q: Which network operators does this antenna specifically support? 

A: As long as the carrier network operates within the 700-2700MHz frequency band (such as China Mobile's Band 3/8, China Unicom's Band 1/3, China Telecom's Band 1, etc.), and your device's RF module supports the corresponding standard, this antenna is compatible. It enhances the physical signal and does not differentiate between carriers.

Q: Does it support 5G networks?

A: It does not support major new 5G frequency bands. The highest frequency of the GLFPC033 is 2700MHz, while the mainstream 5G NR Sub-6GHz bands (such as n77/n78: 3300-4200MHz) are higher than this range. However, it can be used in the 4G (LTE) network connection portion of 5G devices that requires backward compatibility.

Q: Is IPEX or soldering better?

A: It depends on your needs. IPEX connectors facilitate production line assembly, testing, and subsequent maintenance, making them suitable for mass production. Direct soldering provides a more robust connection, lower cost, and smaller footprint, suitable for designs with high reliability and cost control requirements.

Q: What are the most important considerations for PCB layout?

A: The most crucial point is to reserve the correct and sufficient clearance. It is essential to strictly follow the design guidelines, completely clearing all PCB layers below the antenna radiator (especially the ground plane), and ensuring the area around the antenna is kept away from metal components, batteries, and sources of interference.

Q: Will a 3dBi gain affect the communication distance?

A: For this type of small omnidirectional antenna, 3dBi is an optimized typical gain value that balances performance and size. The actual communication distance is determined by the full system link budget. With a proper RF front-end design, it can adequately meet the communication needs of most IoT and mobile data terminals.

Q: How to secure the antenna inside the device?

A: It is recommended to use dedicated thin double-sided tape (such as EMI shielding adhesive with conductive backing or 3M 9448 series) to smoothly attach it to the inner wall of the device housing or an internal non-metallic bracket.
