SPE-23-8-245-A 

The patent pending AFXP125 embedded flexible antenna is a next generation, active multi-band GNSS antenna designed to cover working constellations in the GNSS L1/L5 spectrum. The AFXP125 comes with active circuitry, so it is a plug and play alternative to customer’s design a complex active circuit themselves. The AFXP.125 multi band GNSS antenna is a compact high precision solution for navigation or asset tracking devices where board space is at a premium and cost is a major factor. 

The AFXP125 is a linear polarized antenna, however it has an omnidirectional radiation pattern making it less sensitive to device orientation allowing it to be installed in areas where a patch antenna won’t work. It comes with a low noise figure to preserve signal quality which helps minimize time to first fix, allowing the device to pick up a location as soon as possible. It also features excellent out-of-band rejection to prevent out-of-band signals from overdriving or damaging its LNAs. 

This antenna is made of durable, flexible, polymer with a cable and connector for easy installation. It is designed to be mounted directly to the inner shell of a plastic housing or glass enclosure/cover. No space is needed on the PCBs of your device, but at least 20mm of minimum clearance is required from the groundplane to achieve optimal antenna efficiency. At 76mm*47mm*0.15mm, the antenna is ultrathin and can be applied by a simple peel and stick process, attaching securely to non-metal surfaces via 3M adhesive. It has been tuned to work directly on ABS/PC plastic housings. 

The antenna comes with its filter and LNA design making an ideal multi band GNSS antenna solution for compact high precision automotive navigation or asset tracking devices where board space is at a premium. 

Typical Applications 

- Telematics & E-Mobility 

- Fleet Management & Asset Tracking 

- Navigation & handheld devices 

Cable type, length and connectors are fully customizable. Please contact your regional Taoglas customer support for further information.
