Novel MIMO Antenna System for Ultra Wideband Applications

The design of a 4 × MIMO antenna for UWB communication systems is presented in this study. single element comprised fractal circular ring structure backed by modified partial ground plane having dimensions 30 mm2. has wide impedance bandwidth 9.33 GHz and operates from 2.67 to 12 GHz. Furthermore, the gain increases as frequency increases, with peak realized efficiency 5 dBi >75%, respectively. For applications, array designed analyzed. elements are positioned plus-shaped configuration provide pattern well polarization diversity. It worth mentioning that good isolation characteristics achieved without utilization any enhancement network. proposed was fabricated tested, results show it provides response 2.77 over between more than 15 dB. Based on performance attributes, can be said suitable applications.
