5G Millimeter Wave Technology: An Overview

Wireless communication technology is continually evolving to satisfy the expanding expectations of users. Existing wireless systems will see increased overhead as a result of this. This is reflected in the ongoing development of wireless networks to meet rising capacity demands. As the number of users grows, cellular bands become more congested; as a result, Extremely High Frequency (EHF) bands like mmWave are gaining popularity for use in cellular networks. In next-generation networks, millimeter-wave (mmWave) bands can handle multi-gigabit rates for high-bandwidth applications. These bands have some limits, such as the inability to travel great distances or penetrate buildings or other things. These limits can be used to enable more secure communication while also allowing for high-frequency reuse. This will make spectrum usage more efficient and help with the design of tightly packed systems. This paper reviews the basic concept of the 5G MMW microstrip antenna along with the spectrum defined by the Federal Communications Commission (FCC) for 5G. Also, the challenges and applications of the MMW are cited.
