A novel 4-element MIMO antenna be designed,which conforms to the communicating stand-ards of 802. 11ac for WLAN, in other words, called 5G WiFi. The antenna operates in the 5GHz band. The antenna system was made up of four microstrip patchs,a cylindrical cavity was etched out un-derneath the center of patch. The overall dimension of the antenna was 100 × 50 × 0. 8mm3. According to the result of simulation,the design of MIMO antenna has a minimum bandwidth of 260MHz and the minimum isolation of 31. 8 dB between its antenna elements. The maximum gain for a signal element is 1. 42 dB. The proposed antenna can be used in handheld and other small wireless devices using WLAN in 5 GHz band.
