Abstract
A dual-band two-element Multiple-Input-Multiple-Output (MIMO) antenna for Wireless Local Area Network (WLAN) applications is proposed in this paper. The MIMO antenna consists of two closely arranged symmetric monopole antennas with edge-to-edge distance of only 5.3 mm (0.044λ at 2.51 GHz). To enhance isolation, a decoupling network is inserted between the two antennas without increasing the footprint. The -10 dB impedance bandwidths in lower and higher frequency bands are 2.46-2.7 GHz and 5.04-5.5 GHz. Compared to previous works, the presented decoupling structure can obtain higher isolation over 30 dB in dual bands. Measured results agree well with the simulated ones.
