Design and Implementation of A MIMO Smart Antenna A Candidate for Green Technology

In this paper, Dielectric-Loaded Microstrip Patch Antenna (DL-MPA), has been synthesized and analyzed, which is also referred as “MIMO Smart Antenna” In the designing procedure, three different antennas are designed and simulated. Firstly, “Antenna 1” is a RDRA (Rectangular Dielectric Resonator Antenna) which has been simulated using only one probe coaxial feed technique. Secondly, “Antenna 2” RDRA has been simulated using multiple ports, in addition to the previous excitation it has been excited using other two, strip feed coaxial probe ports. At last, bandwidth improvement method has been implemented to a MPA, and multi frequency operability has been obtained, referred as “Antenna 3”. Experimental approach has been implemented to support antenna analysis and obtained simulated results. Antenna parameters such as return loss, VSWR plot and EH field has been plotted and studied to obtain characteristics performance of the radiating structure. Antenna offers operability at frequency range of 1.5GHz, 3.32GHz and 4.14GHz and having return loss of -21.82dB, -17.48 dB and -36.32dB respectively, and radiation efficiency of the system ranges from 99-135%. These results verify the use of proposed antenna in different frequency of operation; The obtained performance of proposed design, confirms the practicability of antenna in different indoor/outdoor wireless applications. Suitability and applicability of antenna has been found in GSM and other wireless systems frequency range.
