PublicationAn ultrawideband full flexible 4 elements DGS based MIMO antenna for Sub-6 GHz wearable applications(IEEE, 2024-03)
;Bikash Chandra Sahoo ; ; ;Surentiran Padmanathan ;Sadia Afroz ; ;Soh Ping Jack ;Soumya Ranjan MishraIn this article, a compact wearable quad element MIMO antenna is presented operating at 4.5 GHz for 5G n77, n78, and n79 bands with the use of polyester substrate with a size of 80 × 82 × 0.4 mm3. Here T-shaped defected ground structure (DGS) technique has been utilized to improve the impedance bandwidth along with the reduction of the mutual coupling between the radiating elements. The antenna is evaluated in terms of reflection coefficient, gain, efficiency, and radiation pattern. The proposed MIMO antenna attained a maximum simulated gain of 4.3 dBi, and an efficiency of 96 % in the resonating band.
