A wideband high-isolation four-port MIMO antenna with orthogonal diversity and DGS for 5G sub-6 GHz applications
The 5G NR sub-6 GHz bands n77 (3.3–4.2 GHz) and n78 (3.3–3.8 GHz) are widely used for modern 5G communication systems due to their balanced coverage and capacity. This work presents a compact wideband four-port MIMO antenna employing orthogonal diversity and defected ground structure (DGS) techniques for 5G sub-6 GHz...
