A small aperture-coupled DRA, supporting channels 5 to 11 (6.2 – 8.5 GHz), is proposed for use in a 1x2 array and evaluated when mounted on a 77 × 52 mm anchor node PCB. This study assesses the performance of small DRA antennas, complying with IEEE 802.15.4z-2020. The proposed antenna prototype achieves an average gain of 5 dBi across the bands of interest. The results validate the introduction of 3D-printed DRA antennas in AoA applications based on UWBProceedings paper10.23919/eucap63536.2025.10999645978-88-31299-10-7WOS:001507659900481
