Dual-polarized H-shaped aperture-coupled microstrip antenna for sub-6GHz 5G communication systems

The 5G wireless communication technology is seen as a big change in the business of wireless communication, where 5G is the major phase beyond the current 4G. This rapid revolution motivates researchers to advance communication technologies in software and hardware areas. The performance of radio communications in any wireless device depends on the design of an efficient antenna. So, this thesis presents single element and arrays at 3.5 GHz for microstrip antennas. Where 3.5GHz is the center frequency of the N78 sub-6GHz 5G frequency band. A broadband dual-polarized aperture-coupled microstrip antenna is designed and presented. Aperture-coupled feeding technique is considered to achieve the broadband characteristic. An H-shaped slot is considered, which provides the broadband with a shorter slot length. Based on the best optimized single element, several dual-polarized microstrip antenna arrays are designed in order to enhance the realized gain of the antenna design to meet the 5G specifications. Commercial simulation Studio Suite (CST) and Advanced Design System (ADS) were used to design the single element and planar arrays. Parallel feed techniques were utilized to feed the antenna array providing good antenna performance, which can be used in sub-6GHz 5G handset mobiles and base station systems.
