FAQ

Q: Which specific network frequency bands does this antenna support?

A: Its 700-2700MHz coverage range includes many key frequency bands, such as China Mobile's 700MHz (Band 28) and 900MHz (Band 8), China Unicom/China Telecom's 1800MHz (Band 3), and the globally widely used 2100MHz (Band 1). Specific support depends on the frequency band design of the device's RF front-end.

Q: Can it be used in 5G devices?

A: Not fully supported. The highest frequency of GLFPC075 is 2700MHz, while mainstream 5G Sub-6GHz bands (such as n78: 3300-3800MHz) are higher than this range. However, it can be used in 5G devices for 4G fallback (LTE) or low-frequency band connectivity that requires compatibility.

Q: Is there a performance difference between IPEX connection and soldering methods?

A: When correctly implemented, there is no fundamental difference in RF performance between the two. IPEX connections facilitate production line operations and maintenance; direct soldering provides a more permanent and reliable mechanical connection, and is less expensive and requires less space. The choice depends on your production processes and design priorities.

Q: What is the most critical design rule for mounting this antenna on the PCB?

A: The most important thing is to ensure sufficient and proper clearance. Clearance must be made on all PCB layers (especially the ground plane) directly below the antenna radiator, and the area around the antenna must be kept away from metal components and batteries. Incorrect clearance design is a major cause of antenna performance degradation.

Q: Does a 3dBi gain mean a weak signal?

A: Not necessarily. 3dBi is a typical practical gain for this type of small omnidirectional antenna. Communication distance depends on the full system link budget. With reasonable transmit power and receive sensitivity, this gain is sufficient for most IoT and short-to-medium range mobile communication applications.

Q: How to secure the antenna inside the device? 

A: We recommend using high-temperature resistant thin double-sided tape (such as EMI shielding tape with conductive backing or 3M 9448 series) to attach it to the inner wall of the equipment housing or non-metallic bracket. Ensure the surface to be pasted is flat and clean.
