Compact Low-Profile Wearable Antennas For Breast Cancer Detection

arXiv: Signal Processing, 2018

Many lives can be saved if tumors are detected in early stages, which can result in a bigger chance for recovery. Many patients find it irritating to get regular checkups due to the fact that the majority of the monitoring systems are complicated, not available everywhere and not mobile. Furthermore, for medical field applications, micro-strip antennas are efficient and have flexible properties that are utilized in imaging, diagnosis and treatment. It is known that breast cancer is the most common type of cancer in the world, and the earlier its been detected the better. In the early stages of breast cancer, getting rid of from the tumors is much easier and more guaranteed. Nowadays, the main method that is used in the hospitals for breast cancer detection is the Ultra-Wideband method (UWB). However, Many patients find it irritating to get regular check ups due to the fact that the majority of the monitoring systems are complicated and not mobile.

Breast tumour detection by flexible wearable antenna system

International Journal of Computer Aided Engineering and Technology, 2012

Breast tumour detection using flexible wearable antenna system presented in this paper removes the need for liquid coupling mediums used in conventional systems, leading to a simpler and cost effective imaging device. This is achieved by considering a planar microstrip antenna design on a flexible substrate and optimising the antenna for the skin contact operation. It is shown that systems with a matched coupling medium still have 20% theoretical reflection loss at the skin, which is eliminated in the presented system. Simulation results show threefold increase in the current densities and electric fields in the tumour. Experimental results with in-house breast and tumour phantoms show that the received signal from a tumour has 33 dB maximum and 19 dB average (over 400 MHz range) amplitude above noise level. Theoretical analysis, simulation models, and experimental results for breast tumour detection using flexible wearable antenna system are presented and discussed.

Wearable Antenna for Time-Domain Breast Tumor Detection

International Journal of Technology: IJ Tech, 2021

There is a considerable year by year increase in the number of women suffering from breast cancer. Early diagnosis is important to ensure the survival of patients. This study presents the development of a novel, wearable and flexible multiple input multiple output (MIMO) 2×4 antenna design, which operates at a frequency of 5.5-7 GHz for time-domain breast tumor detection. The antennas are all located in the cup of a bra, which is divided into four quadrants; each quadrant has two antennas for tumor detection. The parameters S11 and S21 for each antenna were measured in the frequency domain. The measured results of S11 and S21 indicate that the antennas worked well both with and without a breast phantom model at the assigned frequency. For antenna five, located in the third quadrant (the quadrant with the tumors), the signal response of the antenna on the breast phantom model had a higher amplitude than that without the breast phantom model. The results demonstrate that the antennas worked well for the detection of the tumors.

Design and Analysis of Wearable Microstrip Patch Antenna Applied for Breast Cancer Detection

International Research Journal of Engineering and Technology (IRJET), 2020

This article presents a new design and analysis of wearable microstrip patch antenna applied to detect breast cancer. The suggested antenna frequency of operation is 2.4GHz. Cotton of 100% has been used as the dielectric substrate in microstrip antenna having 1.6 dielectric constants to make it wearable antenna. Transmission feedline is fed to supply power to hexagonal microstrip patch antenna. Antenna design, analysis and 3D breast models were performed using ANSOFT HFSS EM simulator. The parameters like Bandwidth, return loss (S11) gain and radiation pattern are examined to confirm the application of the suggested antenna design.

A novel textile-based UWB patch antenna for breast cancer imaging

Physical and Engineering Sciences in Medicine/Physical and engineering sciences in medicine, 2024

Breast cancer is the second leading cause of death for women worldwide, and detecting cancer at an early stage increases the survival rate by 97%. In this study, a novel textile-based ultrawideband (UWB) microstrip patch antenna was designed and modeled to work in the 2-11.6 GHz frequency range and a simulation was used to test its performance in early breast cancer detection. The antenna was designed with an overall size of 31*31 mm 2 using a denim substrate and 100% metal polyamide-based fabric with copper, silver, and nickel to provide comfort for the wearer. The designed antenna was tested in four numerical breast models. The models ranged from simple tumor-free to complex models with small tumors. The size, structure, and position of the tumor were modified to test the suggested ability of the antenna to detect cancers with different shapes, sizes, and positions. The specific absorption rate (SAR), return loss (S11), and voltage standing wave ratio (VSWR) were calculated for each model to measure the antenna performance. The simulation results showed that SAR values were between 1.6 and 2 W/g (10 g SAR) and were within the allowed range for medical applications. Additionally, the VSWR remained in an acceptable range from 1.15 to 2. Depending on the size and location of the tumor, the antenna return losses of the four models ranged from − 36 to − 18.5 dB. The effect of bending was tested to determine the flexibility. The antenna proved to be highly effective and capable of detecting small tumors with diameters of up to 2 mm.

A Wearable Microwave Antenna Array for Time-Domain Breast Tumor Screening

IEEE Transactions on Medical Imaging, 2016

In this work, we present a clinical prototype with a wearable patient interface for microwave breast cancer detection. The long-term aim of the prototype is a breast health monitoring application. The system operates using multistatic time-domain pulsed radar, with 16 flexible antennas embedded into a bra. Unlike the previously reported, table-based prototype with a rigid cup-like holder, the wearable one requires no immersion medium and enables simple localization of breast surface. In comparison with the table-based prototype, the wearable one is also significantly more cost-effective and has a smaller footprint. To demonstrate the improved functionality of the wearable prototype, we here report the outcome of daily testing of the new, wearable prototype on a healthy volunteer over a 28-day period. The resulting data (both signals and reconstructed images) is compared to that obtained with our table-based prototype. We show that the use of the wearable prototype has improved the quality of collected volunteer data by every investigated measure. This work demonstrates the proof-of-concept for a wearable breast health monitoring array, which can be further optimized in the future for use with patients with various breast sizes and tissue densities.

Localization of Breast Tumor Using Four Elements UWB Wearable Antenna

Applied Computational Electromagnetics Society Journal, 2023

In this paper, four wearable UWB antennas are designed to detect and locate tumor cells placed within a heterogeneous phantom at different positions. The proposed antenna is operated within the 4.90 GHz to 15.97 GHz bandwidth range. It is fabricated, measured, and nearly matched between measured and simulated results. A cavity is formulated to back each antenna within the proposed detection system for increasing penetration and gain of propagated electromagnetic waves of the antenna design. The S-parameter of the proposed system was used to detect and locate a small tumor. The SAR results show that the absorbed power by the breast phantom tissues satisfies the IEEE standards which confirms the appropriateness of the proposed antennas for breast cancer early detection and localization system.

2012

In this paper, two compact Ultra Wideband (UWB) antennas have been proposed to be in touch with skin for microwave breast cancer detection. The UWB techniques allow for a good shape-identification and allow sensing of dielectric properties differences among tissue types over a very wide frequency band. The UWB antennas are designed and analyzed using CST simulation tool in transient mode to verify antenna parameters improvements. The simulation results indicated the improvement of the antenna response by properly selecting antenna dimensions and antenna shape.
