THE rapid expansion in the millimeter-wave (mm-wave) frequency domain has completely changed the course of wireless communication. One of the most important steps to make smart cities, the Internet-of-Things (IoT), smart homes, and vehicular communication a reality is to use mm-wave frequencies for wireless applications. The rise in the number of wireless appliances has also led to a rise in data traffic [1]. The adoption of mm-wave frequencies enabled several gigahertz of bandwidth, allowing data rate and latency limits to be exceeded. The availability of a broad electromagnetic spectrum and frequency reusability are the most important characteristics of mm-wave deployment [2]. Although mm-wave systems have a shorter effective communication distance than microwave systems due to increased propagation loss, they are sufficient to cover small cells that span hundreds of meters [3]. So, the use of mm-wave systems in providing high-speed wireless connectivity in indoor venues, such as shopping centers, stadiums, and auditoriums, is very effective. To satisfy the network coverage in such scenarios, omnidirectional antennas for mm-wave frequencies are key. High gain antennas are also required to mitigate losses due to obstacles, including walls, buildings, and trees, which makes the mm-wave bands more beneficial as larger antenna arrays can be realized in small form factor.
