High gain patch antenna array using dielectric superstrate for the 5G applications

Abstract

In this work, a novel stacked patch antenna array for future 5G applications is proposed. Initially, a single stacked patch antenna is designed to operate at 26 GHz band while maintaining good performances of bandwidth and gain. Better performances are obtained by stacking the superstrate layer above the antenna structure, thereby improving the gain and the bandwidth. The proposed antenna covers the frequency band from 23.02 GHz to 26.12 GHz resulting in a wide bandwidth with a compact size of 13*12 mm2. Performances of the antenna are improved by incorporating an array of 2 identical elements based on the single designed patch antenna, resulting in a higher gain. The proposed array consists of 2 elements using 0.65 mm AR1000 substrate. The two element antenna array shows a good performance in terms of bandwidth (1.7 GHz) and gain reaching 12 dBi with a size of 13*25mm2. The proposed designs are a great potential application for deployment in 5G generation.
