A novel 4-element Multiple Input Multiple Output (MIMO) antenna designed for upcoming 5G applications is investigated in this letter. The MIMO antenna features four customized rectangular patches using a hexagonal shape and a perforated ground plane created using a square pattern to achieve the desired performance. It is built on a Roger RT/duroid 5880 substrate, with measurements of 24 × 24 × 1 mm3 and a dielectric constant of 2.2. The recommended antenna has been analyzed and simulated using the High- Frequency Structure Simulator (HFSS). It features a broad range of 9.09 GHz, resonating from 24.67 to 33.78 GHz, and a S11 around − 47.73 dB. The suggested antenna also demonstrates a gain of roughly about 5.50 dBi at 28 GHz and achieves elevated isolation below -23 dB. The designed MIMO antenna covers the n257 band (26.5–29.5 GHz) and the n261 band (27.5–28.35 GHz), widely used in various countries. These findings and the antenna's low profile highlight its potential for future 5G applications.

摘要

A novel 4-element Multiple Input Multiple Output (MIMO) antenna designed for upcoming 5G applications is investigated in this letter. The MIMO antenna features four customized rectangular patches using a hexagonal shape and a perforated ground plane created using a square pattern to achieve the desired performance. It is built on a Roger RT/duroid 5880 substrate, with measurements of 24 × 24 × 1 mm3 and a dielectric constant of 2.2. The recommended antenna has been analyzed and simulated using the High- Frequency Structure Simulator (HFSS). It features a broad range of 9.09 GHz, resonating from 24.67 to 33.78 GHz, and a S11 around − 47.73 dB. The suggested antenna also demonstrates a gain of roughly about 5.50 dBi at 28 GHz and achieves elevated isolation below -23 dB. The designed MIMO antenna covers the n257 band (26.5–29.5 GHz) and the n261 band (27.5–28.35 GHz), widely used in various countries. These findings and the antenna's low profile highlight its potential for future 5G applications.
