A Multi-Mode Multi-Port Antenna for WiFi Communication and Direction Finding of IoT Devices
Abstract
In this paper, a Multi-Mode Multi-Port antenna for WiFi communication and direction of arrival estimation is presented. Four independent and decoupled antenna ports are realized using a square patch with a slotted ring. The matching is achieved by using a capacitive load to compensate the inductive nature of the probe feed. Thereby, the antenna system is easily integrable into the plastic chassis of an IoT device. WiFi communication, with MIMO options, can be achieved using different antenna ports. In addition, the direction-of-arrival estimation, using all four antenna ports, is accurate with a root mean square error of 20° in 8-polarization.
