A Comparative Study of Two Different Octagonal Structure-Based Split Ring Resonators

Radio Frequency Identification (RFID) Tags market has led to a rise in various sectors and applications due to significant advantages over other wireless communication technologies. Due to the edge of not requiring line-of-sight communication, RFID has acquired the barcode technology market. With RFID, the process of automatic tagging and advanced tracking have been much easier. This paper presents the results of a split ring resonator with split length in different patterns with the octagonal ring structure. The tags in the study can be used for ultra-wideband (UWB) applications with a frequency range of 3–11 GHz. Two different split rings were compared to analyze the encoding (number of bits) and the RCS of the tag. The encoding capacity is found to be increased from 3-bits to 5-bits with the change in the split pattern.
