Dual-band trident shaped MIMO antenna with novel ground plane for 5G applications

A trident-shaped dual-port high isolation MIMO antenna is proposed. The overall dimensions of the proposed design is 62 x 25.6 x 1.524 mm(3). By utilizing an arrow-shaped strip in between the U-shaped patch along with the defected ground plane, dual-band characteristics is achieved. This design demonstrates dual frequency bands varying from 2.99 to 3.61 GHz and 4.53 to 4.92 GHz with corresponding isolation <=- 25 dB and <=- 16 dB, respectively. The measured realized gain and radiation efficiency of the proposed design vary in the range from 2.96 to 3.14 dBi & 3.69 to 3.84 dBi and 72.68 to 80.24% & 85.22 to 84.64%, respectively. The important diversity parameters such as ECC, DG, MEG, CCL, TARC are studied to verify the practical applications of the design. The group delay analysis is also performed at two different orientations of the antenna. The CST microwave studio simulation software is utilized to theoretically model the MIMO design. Moreover, the prototype design is fabricated for practical validation. This antenna successfully covers the 5G and sub 6G n77/n78/n79 spectrum for high data rate communication.
