I. Introduction
The extreme end of the radio spectrum is made up of mm-Wave and microwave regions. While the microwave band extends from 300 MHz to 30 GHz, most conventional and traditional cellular and wireless communications have been utilizing the lower regions of the microwave band [1]. As the digital world enters the era of the Internet of Things (IoT), wireless technology is increasingly becoming the backbone of IoT. This has resulted in increased applications of radio frequency (RF) spectrum and congestion of the microwave band. These bandwidth congestion challenges can only be resolved by using more bandwidth at much higher frequency bands [2]. Latest research into the millimeter - Wave spectrum which stretches from 30 GHz to 300 GHz and with wavelengths from 10mm to 1mm has become one of the hottest topics in recent wireless technologies [3].
