A compact multiple-input-multiple-output (MIMO) antenna that covers the WLAN (2.4GHz) and UWB (3.1{10.6GHz) bands for wireless device applications is presented. The proposed antenna consists of two open L-shaped slot (LS) antenna elements and a narrow slot on the ground plane. The antenna elements are placed perpendicularly to each other to obtain a high isolation, and the narrow slot is added to reduce the mutual coupling between antenna elements at the WLAN band (2.4GHz). The presented MIMO antenna has a small size of 40£40mm 2 , and the prototypes of antenna is fabricated and measured. The measured results show that the antenna has an impedance bandwidth of larger than 2.4{10.6GHz with the mutual coupling less than 20dB in WLAN band and 18dB in 3.1{10.6GHz, making the antenna a good candidate for portable applications.
