Higher isolated dual band notched UWB MIMO antenna with fork stub
In this paper, dual band notch Multi-input Multi-output (MIMO) System of two U-shape patch antennas has been evolved for the UWB application. Spacing between two elements of antennas is 0.270λ0 at 3.1GHz for the UWB operation. To enhance isolation and increase bandwidth impedance, a fork shaped stubs added in the ground plane of the antenna. Due to interference with WIMAX (3.3-3.7 GHZ) and WLAN (5.2-5.8 GHz) on UWB dual band notch function is perform. For achieving the dual band notch characteristics, trekking slots cut in the patch with a feed and C-shaped strip are placed adjacently to the feed line of the antenna. Due to a fork shaped stubs in ground planes, reducing of mutual coupling between elements S21 ≤ -20dB. Peak gain, Efficiency of antenna also investigated and it shows that the proposed MIMO antenna has pleasant characteristics of UWB application.
