Abstract
manuscript presents a novel ring resonator (RR) based coplanar waveguide (CPW) fed four-port MIMO antenna, working around LTE 1.8 GHz and sub-6-GHz 5G applications. The presented MIMO antenna is a based on the microstrip technology and RRs are located on the upper and bottom side of plane of the designed antenna for achieving high isolation and wider bandwidth. The bandwidth and isolation can be adjusted by changing dimension of RR. The total prototype size of proposed MIMO antenna is 30 × 30 × 1.6 mm3 and measured B. W. (S11 ≤ -10 Db) of 0.46 GHz (1.77-2.23 GHz) and 2.45GHz (4.09-6.54 GHz) respectively. The presented MIMO design offers high isolation of -18 dB at both resonating bands. For the purpose of validating the results, planned MIMO antenna design is made-up and tested. A comparison among simulated and tested values of designed antenna has been carried out, and it has been found that they are in good agreement with one another.
