A Wideband Omnidirectional MIMO Antenna for WiFi-6E Applications

A wideband omnidirectional multiple-in multiple-out (MIMO) antenna for WiFi-6E applications is presented in this letter. The antenna operates at 2.37-3.04 GHz (24.7%) and 4.8-7.84 GHz (48.1%), which can cover WiFi-6E triple bands. An array including eight antenna elements is formed around a router. The antenna element has a planar structure with a compact size 48 × 8 × 1 mm
