Abstract	This paper presents experimental work on Ultra Wideband indoor positioning in presence of different objects using a compact UWB antenna using time of arrival positioning techniques. Obstacles considered are wooden table, laboratory chair and a solid wooden object. Different objects affect the accuracy in positioning depending upon the shape, size, and material of the objects. Results show that the error is similar in the presence of laboratory chair and wooden object though the material type is different. This is attributed to the fact that the propagation between Base Stations and Mobile Stations are affected due to height of objects and position of the Base Stations which leads to reflections/ multipath. Maximum error of 5 to 6 cm in localisation is achieved in presence of a wooden block which is due to the fact of having height more than the Base Stations and Mobile Station bringing them in non line of sight situation. Minimum error obtained is 1 to 3 cm when no object is present in the area where localisation is taking place.
