The present invention relates to a WLAN band MIMO antenna using an L-shaped slot, and more particularly, to a WLAN band MIMO antenna using an L-shaped slot, the L-shaped slot having a side opened and formed at one side edge of a substrate ground plane, And two microstrip feed lines formed on the substrate conductive surface and electrically connected to the L-shaped and n-shaped slots through vias are provided in a symmetrical configuration on the substrate, In this open L-shaped slot, an n-type slot is added so that the microstrip-fed antennas are arranged symmetrically with respect to each other, so that the two antennas perform the same performance. To minimize the coupling between the two antennas, The WLAN dual-band MIMO antenna can be manufactured.
