In today’s world, Chipless RFID has created a new era of technological advancement in the field of IoT and sensor applications. The main reason for the booming of RFID technology is that comparatively less expensive and flexible in printing. This technology is also capable of bit-storing and bit-transforming in a user-friendly manner. Chipless RFID also works as a passive sensor because of its varying RF characteristics. In this work, an inverted ‘G’ shaped resonator is proposed and 6 consecutive peaks of resonating frequency are achieved covering UWB and ISM bands from MHz range to GHz range covering a wide band of frequency. The inverted G shape resonator patch is the combination of a number of concentric spirals of copper transmission line over a FR4 substrate. The Radar Cross Section (RCS) is obtained with 6 peaks and considered as the frame of data for bit transformation. Another method is also proposed to calculate the bit density and the bit-capacity to prove the novelty of the tag. This tag resonates a 547, 642, 860, 960 MHz, 1.1, and 1.3 GHz, and with is particular frequency the current distribution is demonstrated. This tag has the speciality to covering the frequency of 547 MHz to 1.8 GHz covering from low frequency to high frequency. The sensor which follows Zigbee protocols normally operates in this range. Covering this band is an important novelty of this tag.
