Abstract
In this research, an L shaped four port MIMO antenna with chip resistor assisted H decoupling is designed. The proposed four port Multiple Input Multiple Output (MIMO) antenna can be applied over both 5G and 6G communication systems in the frequency range of 10 GHz–300 GHz. The antenna can resonate at three different frequencies such as 68.6667 GHz, 90 GHz, and 106.20 GHz. The MIMO antenna is intended on the Rogers RT DUROID 5880 substrate with a thickness of 0.5 mm, the relative permittivity of ε r = 2.2, and loss tangent of tanδ = 0.0009 and a Coplanar waveguide feed line is employed. The whole dimensions of the proposed antenna model is 20.6 × 22.5 × 0.5 mm3. To attain better isolation, T shaped defected ground structure (TDGS) is used in this research. The proposed antenna is analyzed under different parameters such as gain, return loss, Voltage Standing Wave Ratio (VSWR), axial ratio, and other diversity performances of MIMO antenna like Envelope correlation coefficient (ECC), Total Active Refection Coefficient (TARC), Mean Effective Coefficient (MEG) and Diversity Gain (DG). The proposed antenna can obtain return loss values of −18.5540 dB, −31.1488 dB, and −42.0233 dB at the resonating frequencies of 68.667 GHz, 90 GHz, and 105.2 GHz.
