Abstract
A wideband, multi-standard MIMO antenna with hexagonal geometry and slot is proposed for DCS/PCS/LTE/UMTS applications while keeping the real time application at prime to provide high data rate, low latency, high capacity, non-line-of communication, and reliability with continuity. The designed prototype covers 1.64–2.50 GHz frequency band with percentage bandwidth of 41.55% and resonates at 2.1 GHz. The isolation of more than 10 dB is achieved in the 2:1 VSWR frequency band. The total bandwidth of the MIMO antenna is 860 MHz. The designed MIMO has peak gain of 5.4 dBi, ECC 88%, and total efficiency > 71%. The TARC active bandwidth is 600 MHz with best excitation angles of 45°, 45° at ports. The hexagonal slot is used for the control of induced current for better isolation. The proposed MIMO antenna evaluates the SAR performance at resonant frequency for listening, holding, and watching positions, and is found under the required safety norms.
