A Novel Cow-Head Shaped Multiple Input Multiple Output Antenna for 5G Sub:6 GHz N77/N78 & N79 Bands Applications

Abstract

The present work proposes a novel cow-head shaped multiple input multiple output (MIMO) antenna for 5G sub:6 GHz applications, which include N77/N78 (3.3–4.2 GHz/3.3–3.8 GHz) and N79 (4.4–5.0 GHz) bands. The proposed work is designed and developed on a 30×66 mm2 size FR4 substrate with a dielectric constant of 4.4 and loss of tangent of 0.002. The proposed design works in the region from 3.3 to 5 GHz, and an isolation above 18 dB is attained. The parametric analysis and surface current distribution are studied for the optimization of parameters, and the coupling between elements is analyzed respectively. The performance of the design is studied in terms of efficiency (≥ 91.5%), peak gain (3.1–4.6 dBi), and radiation patterns (E & H fields). The diversity parameters (ECC, DG, TARC, CCL, & MEG) are calculated and checked, the same as measured results. Then all the measured results of the fabricated prototype are compared with simulated ones, and they are in good agreement.
