Abstract
Two different leaky-wave antenna topologies are proposed for 2D Direction-of-Arrival (DoA) estimation in the frame of Internet of Things (IoT). The theoretical and simulated results are obtained for the Bluetooth Low Energy (BLE) advertising channels frequencies (i.e. channels #37, #38 and #39 at 2.402, 2.426 and 2.48 GHz, respectively). The synthesized frequency-scanned beams are presented for the two designs, one using four ports and the other using only a single port. The localization performances of each topology are also compared.
