2.4GHz FPC Antenna (1.86dBi) for XIAO nRF54L15

This Seeed 2.4 GHz flexible FPC antenna with IPEX 4 connector is designed for the XIAO nRF54L15, offering 1.86 dBi gain to improve BLE stability and extend range in a slim, space-saving form factor.

This Seeed 2.4 GHz flexible FPC antenna is designed specifically for the Seeed Studio XIAO nRF54L15, providing a compact and reliable external antenna option. With a gain of 1.86 dBi and an IPEX 4 connector, it offers a simple way to improve wireless performance without increasing the size of your project. By moving the antenna outside the board, BLE link stability is noticeably improved, and operating range can be extended, making it especially useful in space-constrained or enclosed designs. The slim, flexible form factor allows the antenna to be positioned for optimal signal performance, while the Ø0.81 × 50 mm coaxial cable keeps installation tidy and unobtrusive. This antenna is well suited to BLE applications where consistent connectivity and compact design are important, such as wearables, smart sensors, and portable devices built around the XIAO nRF54L15. We also sell the XIAO nRF52840 & Wio-SX1262 Kit for Meshtastic which you can grab here. Features
