In this article, a two-element wider-band MIMO consisting of flower shaped antenna (FSA) structure is proposed. The isolated FSA resonance due to the arrangement of symmetrical of elements inter connected with ground additionally low frequency mode appear in MIMO system. Utilizing this type of mode, the flower shaped MIMO radiator operates in frequency range of 2.60-4.42 GHz (impedance bandwidth = 58.7%). The proposed two-element MIMO system occupies compact total area of 0.13λ 2 0 and has observes that no complexity of decoupling scheme. The proposed MIMO structure have thought the band of operation satisfactory of inter-element mutual coupling (isolation) (≥15 dB) & directional pattern with an average gain 3.8 dBi is achieved. Furthermore, mean effective gain (MEG) ratio approaches to unity and, Envelope Correlation Coefficient (ECC) is less than 0.1 are obtained in the corresponding working frequencies, confirming satisfactory diversity performance/MIMO.
In upcoming days wireless communication products and electronic gadgets are becoming a necessity to human life. Communication systems need antennas that work with multiband and wide band with required parameters like polarization and gain. The main motto of this work is to produce high beam forming with the aid of mutual coupling among the four antenna elements in order to encourage enhanced transit capacity and empower the communication bandwidths at very large data rates for 5G Technology. In the view of mitigating the multipath fading with above mentioned principles. The designed antenna is developed a MIMO patch antenna with wide characteristics. It operates the frequency band from 2.2 GHz to 4.8 GHz. The antenna is developed with FR4 material with a dielectric consistent of 4.4, loss tangent of 0.02 and a density of 1.6mm. The recommended design has 4 monopole antennas. Each monopole antenna has a circular patch with radius of 5mm to avoiding interference. The simulation results s- parameter, VSWR, TARC, ECC, CCL and diversity gain are obtained and verified with the aid of Ansys HFSS and CST studio.
