IEEE Transactions on Antennas and Propagation, 2023
The sixth generation of wireless fidelity (Wi-Fi 6) spectrums possess two unbalanced bands of 2.4–2.5 GHz (4.1%) and 5.15–5.85 GHz (12.7%). Most of the existing dual-band Wi-Fi 6 patch antennas are with either a superfluous lower or an insufficient ...

IEEE Internet of Things Journal, 2023
A novel 2-D indoor location system for Internet of Things devices employing a single Wi-Fi access point (AP) is presented. The $\{x, y\}$ position is estimated with a combination of Direction-of-Arrival (DoA) and Time-of-Flight (ToF) algorithms.
