In this study, the effects of the position and the gap orientation of the split ring resonator (SRR) structure, which is applied as a superstrate, on transmission characteristics (i.e. S21 ) are investigated numerically and experimentally. For that purpose, the left edge of the transmission line has been designated as the reference line and the SRR structure is shifted towards both left and right for three different gap orientations. Subsequently, S21 characteristics of the SRR structure having several substrate thicknesses and several substrate dielectric constants are investigated parametrically for three different gap orientations. The results reveal that the position and the gap orientation of the SRR structure have effects on the amplitude and the resonance frequency observed in S21 . Moreover, it has been observed that the substrate thickness and the dielectric constant of the loaded SRR have significant effects on S21 in terms of amplitude and the resonance frequency. Lastly, transmission, reflection, and power distribution plots together with radiation patterns are investigated for three gap orientation cases to reveal power distribution mechanism. In general, this study verifies the literature, combine the analyses as a whole for fairer comparison due to the fact that the analyses have been concerned on the same characterization setup, and fill the gaps by completing the missing analyses. This comprehensive study is believed to be a useful guide for researchers in their studies conducted on sensor and filter designs.
