 restricts the number of radiating parts, is a major limiting issue in this technology. This is owing to the fact that great plane isolation is maintained. This method ensures strong isolation between the ports and can result in directive patterns from each MIMO antenna element. As a result, the final design is ideal for pattern diversity. The technique is applied to an IFA antenna, and 4 and 6 element MIMO antennas are simulated and built to prove the validity of the suggested technique. The simulation and measurement agree well, which supports the validity of the suggested technique. This technology could be a suitable fit for designing huge MIMO antennas for IoT and 5G systems that demand a large number of antennas in a small space. 5G Wireless Communication System in Healthcare Informatics REFERENCES 1.
