Circular Slotted Ring Shaped Mimo Antenna For Ultra Wideband Applications

A MIMO Orthogonally arranged two-element antenna consists defected ground structure is designed and analyzed in this article. The proposed antenna which is orthogonally placed with low isolation is designed to operate in frequency range from 3.6-11.0GHz which also covers UWB frequency range nearly. The Designed antenna is used to cover the many applications like WiMAX, WLAN, under ultra wideband range. The designed antenna consists a partial ground with two circular rings which is excited by using micro strip line feeding. The proposed MIMO antenna works in all c band and x band applications which are very useful for mobile and satellite applicatiopns. The obtained result show that antenna's impedance bandwidth 102% from3.6-11GHz i.e., at ultra wide band. The antenna gives maximum gain of 5.4dBi at 8. 2GHz. ANSYS HFSS software is used for design of it and the results are analyzed. Parameters like reflection coefficient, e-field radiation patterns and current distributions are discussed. From the results it is observed that this antenna application is suited for hand-held and portable mobile applications in day to day life at ultrawideband technology.
