Abstract
In modern wireless technology, optimum antenna structures are essential which response with high data rates, quality performance, and good reliability. A 4 × 4 MIMO antenna is designed, fabricated, analyzed, and proposed. FR4 material has been utilized for the commercialization. The distance between four elements is carefully designed to receive optimum isolation. Square ring-shaped defected ground structure (DFS) is introduced to achieve desire isolation. The radiation characteristics of the resonator have been carefully handled through iteration in the slot and patch dimensions. The proposed radiator exhibits dual-band response with moderate gain of 2.12 and 2.96 dBi. The computed efficiency of 80.37% and 83.48% has been recorded for 4.46–4.57 GHz frequency band and 4.95–5.03 GHz frequency band, respectively. The other output parameters such as MEG, CCL, and ECC are also having prominent values. There is a very close correlation between the software computed return loss values and actual values. The presented antenna is best suitable candidate for 5G sub-6 GHz and Wireless Local Area Network (WLAN) applications.
