Dual UWB Antennas on AoA Anchor Node

This paper investigates the impact of mounting UWB antennas on small anchor nodes for angle-of-arrival indoor positioning systems. A slot and monopole antenna supporting UWB channels 5 to 10 (6.2-8.6 GHz) are evaluated when connected to a 76.6 x 51.6 mm anchor node PCB. The study assesses the performance of compact slot and monopole antennas, complying with IEEE 802.15.4z-2020 standards. The results provide valuable insights into optimizing UWB antenna performance for AoA applications.
