ABSTRACTA multiple‐input multiple‐output (MIMO) slot antenna integrated with a printed circuit board (PCB) is proposed for access‐point (AP) applications. The antenna comprises two square slot radiators fed by mutually orthogonal 50‐Ω microstrip lines. Through an appropriate adjustment of the antenna geometry parameters, a sufficient −10 dB return loss impedance bandwidth (∼21% at 2.43 GHz), a good radiating performance (i.e., high antenna peak gain values and stable radiation patterns), and a high isolation between the radiators can be achieved. The antenna is thus ideally suited for IEEE 802.11n (2.4 GHz) wireless local area network (WLAN) AP applications. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:1254–1256, 2016
