Abstract
A simple H shaped MIMO antenna with side to side spacing of 6 mm with three pair of unequal length of slits in the ground plane is designed at 5.8 GHz for WLAN application. A pair of unequal slit length is etched in the ground plane to reduce the mutual coupling between the MIMO antenna element is studied and proposed in this paper. High isolation of more than 45 dB is achieved using this proposed design. The MIMO antenna is spaced 0.311λo apart from the center sharing the same ground plane. The isolation is increased from 24 to 46 dB with the help of unequal length of slit in the ground plane. The structure is fabricated on the 40 mm × 24 mm finite ground plane leading to small size and coaxial feeding is used to feed the patch. The proposed design is simple to construct on FR4 substrate leading to low cost with an advantage of high isolation. The proposed H shaped MIMO structure is fabricated and tested. The effect of various parameters such as spacing between slits, the width of the slit, number of slits of equal length and unequal length of slits on mutual coupling is studied.
