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

Abstract

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.
