Design of a novel 5G MIMO antenna with its DGP optimisation using PSOGSA

Abstract

ABSTRACT In this manuscript, the design of a high isolation Multiple Input Multiple Output (MIMO) Hybrid Fractal Antenna (HFA) has been presented for 5 G and other wireless standards in a wider operational frequency range from 1 to 30 GHz. The fractional ground plane is used for the assembly of the antenna in the initial phase, further, the T-stub has been exploited on the ground plane to expand the isolation between the radiating elements. The dimensions of the proposed antenna are optimised using the Particle Swarm Optimisation Gravitational Search Algorithm (PSOGSA). The performance parameters of the projected antenna have been measured and analysed. The obtained experimental results are highly correlated with simulated ones. Performance diversity parameters of designed antenna like CCL, DG, ECC, TARC, and MEG fall within working limits in the frequency range of interest. The developed antenna retains high isolation between −30 to−50 dB in the desired frequency range. The proposed model of an antenna can be useful for 5 G 3.5 GHz band, 5 G NR (New Radio) frequency bands (3.3–5.0 GHz), LTE band 46 (5.15–5.925 GHz), European Union 5 G frequency band (5.9–6.4 GHz), 5 G 26 GHz frequency band and other wireless standards in the frequency range from 1 to 30 GHz.
