Design and Analysis of Simple Compact MIMO Antenna for Ultra-Wide Band Application

The proposed research presents a compact two ports Multiple Input Multiple Output (MIMO) antenna for the Ultra-Wide Band Application. The two symmetrical radiators consist for presented antenna and developed on an FR4 substrate for the overall size of the antenna is 20 × 44.1 × 1.6mm3 . The microstrip line is fed with a 50Ω for the proposed antenna. The lower than isolation is < −25 dB from 3.1 to 10.6 GHz. The gain is 4.3dB and The Envelope Correlation Coefficients (ECC) < 0.01. The radiators for the better isolations used for the F-shaped stub. The size of the vertical block of stub is 12.3 X 5 mm. Antenna parameters are evaluation for the return loss, ECC, DG, gain, radiation pattern and isolation.
