In the given paper, a MIMO antenna with three ports is presented which occupies a volume of 31x27x18mm3. The proposed antenna contains three individual antenna segments connected at the center and forms a Y-shaped structure with CPW fed flag-shaped radiating elements. The antenna attains the -10dB impedance bandwidth ranging from 5.93-16.36 GHz that covers the part of C-band and X-band respectively. The radiation performance of the antenna is also analyzed for various operating frequencies for single antenna and MIMO antenna to study the pattern and noticed bidirectional patterns in the azimuth plane. The simulation results prove that the antenna operates with a maximum peak realized gain of 5.96dB, 6.85dB, 6.52dB in MIMO mode in the operating band of the antenna.
