Flexible Uwb Amc Antenna for Early Stage Skin Cancer Identification

Abstract

This work involves designing an antenna that meets the requirements of radar systems. The associated technology, which was for a long time reserved for the military field, is now available in the civil field, as well as in the biomedical sector for the development of "monitoring" systems allowing to monitor the state of health of a patient in a non-invasive way. The goal of this article is to design a wearable textile antenna to detect cancerous tumors of a patient without direct contact with the skin taking into account the electromagnetic waves directed towards the human body due to the difference between the dielectric constants of healthy and unhealthy tissues. Here we present a miniature AMC antenna of rectangular shape that satisfies the UWB characteristics in terms of bandwidth and reflection coefficient. The proposed AMC antenna operates in X-frequency band (8-12 GHz). Using a model of dielectric artificial skin, we have simulated the specific absorption rate on the human body in order to better respect the FCC standards allowed 1.6 W/kg averaged to 1 g of human tissue.

Recent Advances in Wearable Antenna Technologies: A Review

“…In [85], Mersani et al introduced a compact monopole antenna to diagnose skin cancer in a person afflicted by xeroderma pigmentosum diseases for use in radiography. The proposed antenna reacted successfully with the specified criteria and showed UWB behavior.…”

“…Section 2 investigated the performance of textile wearable antennas with respect to their size, substrates, and frequency bands [29, 37, 42-44, 46, 57, 59, 60]. Furthermore, the bending scenarios of antennas in several radiuses and the impact of bending on the efficiency were addressed in Section 3 [59,67,70,71,73,79,85,[91][92][93]. On the other hand, Section 4 exposed the high conductive substrate materials and discussed their effect on the design and fabrication of different wearable antennas [111, 115-119, 124, 125, 132].…”

ON-OFF Body Ultra-Wideband (UWB) Antenna for Wireless Body Area Networks (WBAN): A Review

“…Wearable technology is a growing area of innovation that can reduce medical mistakes and enhance the standard of patient healthcare. To diagnose skin cancer in a person afflicted by xeroderma pigmentosum disease, Mersani et al [52] suggested a miniature monopole antenna for use in medical imaging to discover the cancerous tumors without contacting the skin concerning the electromagnetic signal radiated towards the human body. The overall dimension of the antenna was defined as shown in figure 18 based on flexible Zelt, tin/copper textile substrate material.…”

“…Section III concentrates on (ON-Body) communication antenna analysis and applications [70]- [86]. On the other hand, the paper classified and considered the operating frequency bands standard by 802.15 family and Federal Communications Commission (FCC) [32] UWB for OFF-Body based monopole [33], [34], [36], [40], [42]- [44], [47]- [49], [52], [54], [55], ground plane [57], [58], [63], [68] and ON-Body antennas [71], [74]- [77], [79], [81], [84]- [86]. Finally, the conclusion of the whole article is presented in section IV.…”

Microwave Imaging of Breast Skin Utilizing Elliptical UWB Antenna and Reverse Problems Algorithm

“…Despite detecting a tiny tumor having high resolution, the antenna system was complex, and the RF components were expensive at those high frequencies compared to the microwave region RF components [14]. A flexible AMC antenna designed for early detection of skin cancer was designed at the X-band and frequency range of 8-12 GHz, the radiation efficiency of 65%, and maximum gain of 6.5 dBi (limited bandwidth so a low resolution was obtained) [15]. Another AMC wearable UWB antenna was designed at the X-band from 8 GHz to 13 GHz to detect a tumor in the skin.…”
