Abstract

This article presents a four-port multiple-input multiple-output (MIMO) antenna using double-sided decoupling techniques. The size of the quad-element MIMO antenna is 36 mm × 36 mm × 1.6 mm. The reflection coefficient is <−10 dB and the transmittance is <−27 dB in the range of 14 to 18 GHz, with a total impedance bandwidth of 4 GHz. Parasitic elements and a defected ground structure (DGS) are used to reduce the inter-radiator transmittance. Parasitic elements are used on the top side of the antenna to minimize transmittance between neighboring elements. DGS is used on the back side to minimize transmittance in both neighboring elements and diagonal elements. The envelope correlation coefficient (ECC) is <0.0075, the diversity gain (DG) is >9.96 dB, and the peak gain is 5.75 dBi. The presented antenna was analyzed in terms of the reflection coefficients (Sij ∈ i = j), transmittance (Sij ∈ i ≠ j), ECC, multiplexing efficiency, DG, and peak gain. Additionally, the design was tested in an anechoic chamber. The proposed design is an acceptable candidate for Ku-band applications after experimental investigations.
