CIQBCP-MIMO-DRA: CSRR inspired quad band circularly polarized MIMO-DRA for W-LAN, Wi-Max, Wi-Fi (6E) and X-band applications

Abstract This paper emphasizes on amalgamation of MIMO antenna with DRA structures; explicitly useful to wireless applications. The feeding mechanism is accomplished by the symmetrically positioned tapered Y-shape lines. The design also encompasses a CSRR geometry along with two metallic reflectors. The incorporation of CSRR introduces novel investigation into traditional designs, resulting in improved isolation performance of the MIMO design. In order to demonstrate the effectiveness of the mentioned antenna, we performed a simulation using ANSYS-HFSS. Subsequently, a physical model was developed and tested. It confirms four different resonating points as 2.56, 4.08, 5.76, and 9.12 GHz with isolations of 36, 47.3, 33.9, and 33 dB respectively. In addition, a few other important parameters relevant to MIMO have been considered and presented in the form of ECC, MEG, DG, CCL, and TARC which claim the dominancy of the stated antenna under the MIMO diversity scenario. In summary, we have presented a model that demonstrates a strong correlation between the simulated and measured outcomes.
