This paper proposes a MIMO circular patch microstrip antenna (CPMA) operating at resonant frequencies of 3.5 GHz and 6 GHz for 5G communication systems. The proposed antenna is designed using RO-5880 substrate with a dielectric constant (εr) of 2.2, a thickness (h) of 1.58 mm and a loss tan (tanδ) of 0.0009. The dual band characteristic is obtained by placing the slot in the center of the CPMA while the inset feeder is used to control the reflection coefficient. Furthermore, mutual coupling reduction is obtained by controlling the distance between the antennas when configured in MIMO. Based on the simulation results, the proposed antenna produces excellent performance with reflection coefficient ≤ – 10 dB and mutual coupling (MC) ≤ – 20 dB at resonant frequencies of 3.5 GHz and 6 GHz. This research is very useful and can be recommended as a receiving antenna for 5G communication system. |
