Abstract
A UWB localization device comprising a UWB receiver with a first and second antenna device for receiving UWB signals from a UWB transmitter; a UWB shield arranged between the antenna devices; and a processing unit. The processing unit is configured to determine, by processing properties of the UWB signals, a first and a second time of arrival of UWB signals from a UWB transmitter at the first and second antenna devices; and to determine a location of the UWB transmitter based on the first and second time of arrival. The UWB shield is configured to cause a delay in the second time of arrival of UWB signals from the UWB transmitter received at the second antenna device. The first and the second antenna devices are arranged with opposing antenna sensitivity patterns.
