Innovative High-Gain Array Antenna Design for Compact 28 GHz Millimeter-Wave Communication in 5G Applications

Abstract

As there has been an explosive increase in wireless data traffic, mm-wave communication has become one of the most attractive techniques in the 5G mobilecommunications systems. In the landscape of 5G millimeter-wave communication, the demand for high-speed data transmission is paramount. In this study, we aim to design and optimize a novel array antenna at 28 GHz, which is an important frequency band for 5G mm-wave applications. In the case of higher frequencies, such array design provides a robust communication link given the enhanced bandwidth and gain. In the quest for the upcoming 5G millimeter-wave communications with stringent antenna gain and beamforming agility requirements, this paper shall present design and measurement of a reduced-size and scalable phased array antenna for the 28-GHz access network. Numerical results on the performance of our antenna are thoroughly studied in this paper, whereas, the significant contributions toward the 5G mm-wave communication are addressed as well. Maximum gain is 9.2 dB, efficiency is 99.5% and the useful bandwidth is 3.5 GHz in the range of interest and is performance is well suited and makes the proposed antenna suitable for next-generation 5G millimeter- wave deployments. Moreover, the challenges that mm-Wave applications meet are evaluated and some innovative mechanisms are also proposed to enhance throughput. We also delve into the antenna's impact on the environment and human body exposure, highlighting broader implications. Lastly, the superior performance specifications of our proposed antenna demonstrate that it still presents a significant enabler of future 5G millimeter wave communication networks, enabling further connectivity and perhaps even fast wireless communication.
