ABSTRACT: The higher frequency spectrum prevalence of the next generation of mobile communication, as well as other new service applications, will likely be dependent upon new advanced antenna technologies. In this regard, the narrow beam widths generally associated with antennas at higher frequencies has led to the study of using advanced multiple-input multiple-output (MIMO) architecture as well as adaptive beam-forming. These antenna technologies may be among the key factors for overcoming some of the challenging propagation characteristics of mm-waves and could increase the spectrum efficiency, provide higher data rates, and adequate reasonable coverage for mobile broadband services. With the potential for higher frequencies as well as mm waves deployment, most 5G frequency bands are predicted to be in the range of 20-50GHz. More specifically, the frequency band of 5G is predicted to be extended from 28GHz to 38GHz. In this paper, our goal is to analyze the design of four elements 28GHz microstrip patch array antenna for future 5G mobile phone applications. The designed antenna can be implemented using low cost FR-4 substrates and can maintain good performance in terms of gain and efficiency. Additionally, the simulated results demonstrate that it has S11 response of less than -10 dB in the 22-34 GHz frequency range.
