Background/Objectives: In this paper, magnetic resonance of a microstrip line loaded with planar square split ring resonator (SRR) and spiral resonator (SR) structure, printed on Rogers RO3010 substrate, has been investigated. Methods/ Statistical analysis: The electromagnetic interaction of resonators with microstrip line is examined by simulating microstrip line loaded resonators inside a waveguide with High Frequency Structure Simulator(HFSS software). Findings: The magnetic resonance in SRR/SR loaded microstrip line shifts to lower frequency region due to loading. Further it is observed that resonant frequency shifts to lower frequency region to a great extent with SR loading as compared to SRR loading. Application/Improvements: The resonant frequency in SR loaded microstrip line is much less than resonant frequency of SRR loaded microstrip line. Hence SR loading can be used to design electrically small antennas.
