Product description
Documentation & resources

The ANT-B11 is a compact antenna board designed specifically for Bluetooth angle-of-arrival (AoA) direction finding systems. It features three-patch antenna elements in an arrangement combining performance and small PCB size. It can measure the angle of an incoming Bluetooth Low Energy radio signal and, depending on the orientation of the antenna board, determine with great accuracy the azimuth or elevation information of a Bluetooth LE device in an indoors environment.

It features the NINA-B411 Bluetooth 5.1 standalone module running u-locateEmbed* - the unique u-blox direction-finding algorithm for high-precision positioning. The digital interfaces of the NINA-B411 module are connected to a standard, widely available pin header, allowing easy connection to an application board, thus forming a complete AoA anchor point.

* Note: u-locateEmbed was previously named u-connectLocate.
