GNSS L1/L2/L5 Adhesive Embedded FPC Antenna
The AC31005 is a linearly polarized, flexible printed circuit (FPC) antenna that delivers robust, omnidirectional performance across all major global navigation systems, including GPS, GLONASS, BeiDou, and Galileo. Its multiband capability enables faster PPP (Precise Point Positioning ) convergence, decimeter-level accuracy in positioning and improved resilience against multipath interference or jamming/spoofing.
The AC31005 delivers excellent efficiency and low VSWR in demanding GNSS applications like precision surveying, battery-powered devices or autonomous systems. Its flexible form factor and peel-and-stick adhesive backing simplify installation, making it easy to integrate into compact or uniquely shaped enclosures.
Connection to the radio module is provided via a 1.13 mm coaxial cable terminated with a U.FL-type plug connector, with multiple cable length options available (see Ordering Information).
