The millimeter wave technology has made its way to the 5G technology as the system of 5G requires larger bandwidth, higher frequency and system capacity. In order to achieve these parameters, the millimeter wave antenna research becomes necessary. The current wireless technologies require huge bandwidth which makes the spectrum of millimeter wave a potential candidate. Microstrip antennas have always been in an increasing demand due to their exceptional performance in the applications of wireless communication. The advantages of microstrip patch antenna led to its popularity among the researchers.The technologies such as MIMO, CMOS and beam forming are used with millimeter wave antenna for improving the mobile phone performance. There are various designs of microstrip patch antenna related to 5G technology and applications in the millimeter wave band which are discussed in the paper.
