Progress In Electromagnetics Research C, Vol. 123, 91-99, 2022
Abstract
This paper describes the concept and implementation of a compact dual-band microstrip slot antenna and its four-unit multiple-input–multiple-output (MIMO) implementation for sub-6 GHz utilizations. The proposed structure comprises a 50 ohm microstrip monopole on the top side with a defective ground structure (DGS) having semicircular and rectangular slots. This quad-element MIMO antenna has a size of 60 × 60 × 1.6 mm3. The proposed antenna provides wide impedance bandwidths of 23.7% (2.42 GHz to 3.07 GHz) for the first band and 42.2% (4.14 GHz to 6.37 GHz) for the second band with a mutual coupling value less than -34 dB for the two bands. The antenna also provides a low envelope correlation coefficient, good antenna gain, and acceptable radiation efficiency across the frequency ranges.
