Abstract:

In this project, an extremely wideband, lowprofile “Multiple-Input Multiple-Output” (MIMO) antenna has been investigated. The proposed antenna possesses four mutually orthogonal tapered fed polygon radiators for achieving a wide bandwidth. Proposed antenna has been designed on Rogers RT / Duroid5880 substrate material having dielectric constant of 2.2, loss tangent 0.009 within size of 30mm x 30mm.The antenna exhibits an extremely wide frequency bandwidth covering 5.3 to 120 GHz with one notch 7.96 to 9.77GHz and offers fractional bandwidth (FBW) of 183.05%.Additionally, Envelope Correlation Coefficient (ECC < 0.002), Diversity gain (DG ~ 10dB), Total Active Reflection Coefficient (TARC < 0.3), Channel Capacity Loss (CCL < 0.2) and -5dB < MEG < -7dB are analyzed for obtaining the high isolation between radiating elements. The proposed antenna is designed and simulated by using the HFSS software.
