An ultra-wideband (UWB) tag is a device that can be attached to objects to locate them or for other operations such as unlocking a device based on proximity to another device. Common implementations utilize at least three antennas on the device that detects a precise location of a UWB tag. This disclosure describes techniques that leverage secondary radiation caused by the metal case of a laptop (or other devices) to accurately locate a UWB tag while utilizing just two antennas, simplifying hardware design and reducing cost.
