I. Introduction
During the past decades, the increasing demand for high-rate data transfer applications such as internet of things (IOT) has led the manufacturers to focus on replacing Fourth Generation (4G) of communication by Fifth Generation (5G) and beyond. In addition to the rate of the data transfer which is aimed to be about Gigabit per second (Gb/s), 5G communication follows the advanced goals of low delay time, cost efficient, and low profile systems. Operating frequency bands for 5G communication according to International Telecommunication Union (ITU) have been considered as (3.4-3.6) GHz, (5–6) GHz, (24.25-27.5) GHz, (37.5-40) GHz, and (66–76) GHz. Moreover, Federal Communication Commission (FCC) has introduced (27.5-28.35) GHz band as another authorized spectrum [1].
