New Compact Broadband SRR Loaded Antenna Pattern for 5G Applications

In this paper, we propose efficient split-ring-resonators (SRRs) loaded circular patch with a central frequency of 28 GHz, terminated by an insulating rectangular slot for 5G communication systems. The. The efficiency features of the antenna, with a Rogers RT5880 substrate of 1.575 mm of thickness, were examined using Computer Simulation Technology (CST). The antenna is developed from the proposed optimized antenna and is tested by using the vector network analyzer (VNA). Through the use of optimization techniques, the bandwidth will increase from 1.93 GHz (27.10 –29.03 GHz) to 3.56 GHz (26.16 –29.72 GHz) by integrating these Split Ring Resonators (SRR). The gain increases from 2.7 dBi to 7.38 dBi when two pairs of Split Ring Resonators are incorporated (SRRs). Our methodology was compared to that of previously published studies. The results are satisfactory, and the suggested antenna is a viable contender for operation in the 28 GHz millimeter-wave frequency spectrum for 5G applications.
