Design and development of a new metamaterial sensor-based Minkowski fractal antenna for medical imaging

Abstract

The metamaterial sensor antenna is numerically designed to detect breast cancer using breast cancer cell lines, especially relying on the electrical characteristics of breast cancer cells, and designed antenna is measured and the results are observed. The metamaterial sensor antenna is a simple and efficient antenna which is designed using the Minkowski fractal curve with a ring-shaped Split Ring Resonator (SRR). The SRR is chosen because of its inductive and capacitive resonating properties. In addition, the Minkowski fractal curve is used as a defective ground structure to improve sensor sensitivity and selectivity. The numerical investigations are based on different iterations of the Minkowski fractal curve. In that iteration, the third iteration of the Minkowski fractal gives better results. The designed antenna is tested with breast cancer cell lines, and it resonates at a frequency of 2.35, 2.42, and 2.52 GHz for different dielectric constants and conductivity. The simulated design antenna is tested with different cancer cell lines like MDA-MB-231, MCF-7, and HS758-T to ensure its performance and selectivity. The measured result of the fabricated antenna shows that the antenna design resonates at the same frequency as the simulated antenna results.

On the devolvement of fractal antenna for IoT applications

“…A Microstrip Patch Antenna (MSA) has many attractive unique features, at the same time it is suffering with narrow bandwidth, relatively large size and single operating frequency [1,2].To address these issues many techniques are proposed in the literature such as slots [3,4], defected ground structure [5,6], PIFA [7,8], and fractal geometry [9][10][11]. Aim of this work is to design a fractal patch antenna with multiband characteristic.…”

“…Dual band fractal antenna for Wi-Max, public safety frequency bands have been presented in [6,23]. A Minkowski fractal geometry based multiband antenna is proposed for breast cancer detection application in [10]. In [24], a Half T-square strip fractal geometry is used to design antenna for achieving multi-functionality in its resonance characteristics.…”

Design and Fabrication of a Novel Corona-Shaped Metamaterial Biosensor for Cancer Cell Detection

“…Metamaterial-based sensors offer significantly higher sensitivity compared to traditional sensors [12][13][14][15][16][17]. Similarly, the properties of metamaterial and fractal forms can be combined to obtain multi-service applications [18][19][20][21][22][23].…”

“…Finally, the characteristics of this biosensor are compared with other resonators existing in the literature [24][25][26][27][28]. Most of this research only covers the simulation aspect without considering the verification of application performance [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28], and this is what we present in this study, in a manner that applies across multiple samples.…”
