Frequently Asked Questions
Q: What wireless standards does this FPC antenna support?
A: This FPC built-in soft antenna supports 2G (GSM/GPRS), 3G, 4G LTE, and NB-IoT standards, covering a broad frequency range of 700–2700 MHz, making it compatible with most modern cellular communication modules.
Q: Can I get a custom cable length or connector type?
A: Yes! Custom cable lengths and connector types are available upon request. Please contact us with your specifications and we will provide a tailored solution. Bulk orders are also eligible for preferential pricing.
Q: How is this antenna attached to a PCB or module?
A: This antenna uses a welding (solder) connector, which allows it to be directly soldered onto a PCB or communication module for a stable and permanent connection. The flexible FPC body can then be routed or folded to fit within the device enclosure.
Q: What is the impedance of this antenna and why does it matter?
A: The antenna has a 50-ohm impedance, which is the industry standard for most RF communication systems. Matching impedance between the antenna and the module ensures maximum signal transfer efficiency and minimal power loss.
