Antenna Characteristics Contributions to the Improvement of UWB Real-Time Locating Systems’ Reading Range and Multipath Mitigation

Indoor object localization and positioning is part of the space-awareness concept which has seen a rising popularity in recent Internet Things (IoT) research applications. This article presents novel method to improve performance ultra-wide band (UWB) real-time locating systems (RTLS) by improving transmitting receiving reader tag antennas. Patch directional UWB antennas with relatively higher gain compared generally used standard omnidirectional monopole have been exploited achieve larger range. Furthermore, patch were designed wideband circular polarization two objectives: received power independent orientation tagged objects that need be detected, filtering unwanted multipath signals. A measurement campaign was conducted using commercially available RTLS conventional then newly comparison between results antenna types demonstrates an improved range almost 100 m difference, orientation, increased mitigation circularly polarized
