“…L is the equivalent inductance loading depends on the length of rings and C is the equivalent capacitance loading determined by the gap between the rings and the splits at each ring. Both capacities and inductive loading are simultaneously applied as an LC tank circuit, and resonance characteristic results an antenna size reduction …”

A new design of compact micro strip antenna, based on a newly structure "E"SRR of metamaterial is proposed and designed using CST Microwave Studio. It has been found that the characteristics of new micro strip antenna with novel designed metamaterials placed in the same plane as the radiating element are comparable to the conventional patch antennas, whereas its gain, directivity, and radiating efficiency are remarkably improved. For the design and fabricated antenna, it shows that with the addition of split ring resonator, the frequency has been shifted from 2.38 GHz to 2.4 GHz. The return loss of this antenna increased from −60 dB to −70 dB. The realized gain increased from 7.1 dbi for the antenna alone to 7.31 dbi for the meta-material antenna. Prototype for all antennas are fabricated and measured. Good agreement between the measured and simulated results is achieved.

“…The assessment of the proposed fractal antenna with other existing fractal antennas is tabulated in Table 3. From Table 3, it can be observed that the antennas designed in [22,23,[28][29][30] are compact in size as compared to the proposed fractal antenna. However, these antennas have less frequency bands and bandwidth than the proposed fractal antenna.…”

This manuscript presents the design of an antenna based on nested square shaped ring fractal geometry with circular ring elements for multi-band wireless applications. The impedance bandwidth and reflection coefficient of the antenna are improved with the design of different iterations from the 0th to 2nd. The performance parameters of the antenna like reflection coefficient, VSWR, bandwidth, bandwidth ratio, and current density are improved in the final iteration. It also achieves the enhanced bandwidth greater than 3 GHz at three resonant frequency bands and exhibits additional frequency band at 2.4 GHz. Likewise, the frequency band of designed fractal antenna shifts towards the lower end and helps in achieving the miniaturization of antenna. The proposed fractal antenna is designed and fabricated on a low-cost FR4 glass epoxy substrate and investigated using HFSS software. The proposed antenna is optimized for generating different parameters, and the last geometry is fabricated and tested. Further, these parameters are compared with the experimental results and found in good agreement with each other. Due to the multi-band behaviour and improved bandwidth, the proposed fractal antenna can be considered as a good candidate for several wireless standards.

Abstract-An SRR loaded compact RFID tag for broadband operation over the UHF RFID band is presented. The tag antenna structure is composed of a dipole whose arms are symmetrically loaded with square split ring resonators (SRRs) along a short circuited strip between the SRRs. The antenna is made inductive and reduced in overall size by the SRR sections. The measured read range characteristics of the proposed RFID tag with an RFID chip Alien Higgs-3 are presented. The proposed tag operates over the entire UHF RFID band about a maximum read range of 7 meters in the entire elevation angular ranges and over wide azimuthal angular ranges.
