In this paper, we present a split ring resonator (SRR) for a nano-aperture antenna for biomedical and spectroscopy applications. We have shown that while the graphene coat layer is carried out to the structure, we are modifying a reconfigurable nano-antenna with more transmittance. The prototyped structure is modeled with the finite difference time domain (FDTD) method by the CST microwave studio and an 80nm thick SiN layer is selected as a substrate with refractive index of 1.98 and the Palik model is used for the gold layer with the thickness of 30nm. Here, we have selected the single graphene layer for a coat with the thickness of 1nm. Here, the sensitivity of the antenna is studied for the incident wave in X and Y directions and we show the dependency of transmittance in the direction of the incident wave. The SiO2 nano-spherical particle is used in various chains formations for improving the transmittance in antenna and improve enhancement and controlling of the electric field (E-field), in X and Y directions. We have checked various nanomaterial effects on the resonances. This nanoantenna is useful for spectroscopy and some medical applications such as detection of skin cancer, which has affected nanoantenna resonance frequency similar to the nanospherical array in this study.
