SHARED CIRCULAR RADIATOR FOR UWB-MIMO APPLICATIONS

摘要

A compact dual-polarized lower ultra-wideband multi-input multi-output antenna made of the shared radiating element is proposed. The antenna is a microstrip line fed and has a dimension 19.5x19.5x0.787mm3 with the partial ground plane. Slots are etched in the radiator and the ground, which helps reducing mutual coupling thereby increasing MIMO performance. Miniaturization is achieved using the partial ground plane. The antenna shows good performance covering a bandwidth of around 11GHz in the ultra-wideband spectrum catering to the requirements of WLAN, WWAN, WiMax, WiFi, LTE-A, ISM, USB dongle applications to mention the important ones. The designed antenna is modeled and simulated using Advanced Design System simulator.
