Metamaterial loaded elliptical ring structured mimo antenna

Abstract

The article proposes a MIMO isolation enhanced MIMO antenna for LTE bands, Bluetooth and Wi-Fi. The antenna is consisting of two radiating elements, where two are similar radiating elements separated by a distance. Another patch element is also added to create the peaks in the return loss. The antenna designed is working in the bands 1.29GHz-3.98GHz, 7.12GHz-8.09GHz, 14.01GHz-15.82GHz and 17.64GHz-20GHz. It has achieved good gain in the working bands of the antenna. The antenna is fabricated on 50×60×1.6 mm^3 FR-4 substrate with dielectric constant of 4.4. The antenna is analyzed and simulated using Ansys electromagnetic desktop 18. The other parameters such as gain, radiation patterns etc. are also discussed.
