Abstract

The design of a printed 5G-MIMO antenna is an emerging research topic in networking and communication domain. In this script, a compact, printed, isolation enhanced, Multiple-Input-Multiple-Output or MIMO antenna for various 5G applications has been investigated. The antenna presented here is just 20 × 20 × 1 mm3 (1.87λ × 1.87λ × 0.09λ, λ being the wavelength of free space) in dimension. RT/duroid-5880 has been utilized as a substrate material. Two copper radiators, have been orthogonally positioned on the top of 1.0 mm thick substrate, for achieving diversity in polarization and radiation pattern. A bifurcated arrow shaped parasitic structure, has been placed between the radiators for isolation enhancement. The final antenna structure reflected a wide bandwidth of 28–56 GHz. The proposed antenna is applicable for 29.1–29.25 GHz, 31.0–31.3 GHz, 37.0–38.6 GHz, 38.6–40.0 GHz, and 42.0–42.5 GHz bands of 5G spectrum.
