Textile Ultra-Wide Band Antenna With X Band For Breast Cancer Detection

Abstract

Objectives: To detect breast cancer with the use of textile materials flexible antenna. Methods: The suggested textile antenna is fabricated with felt, as a substrate, and a conductive fabric: zelt, as a patch and ground plane. Multiple simulations were done in order to obtain an idea about the reflection coefficient, gain, directivity especially the specific absorption rate (SAR), which can valorize the antenna performance and guarantee human security in the presence of electromagnetic waves. The current density results are compared to each other in multiple cases in order to assure the detection process with several size of tumor (from 2 to 8 mm). The antenna works in the X band (from 8 to 12 GHz) which has been dedicated for satellite applications from past many years, radar and many other applications including the medical field where antenna has been used to help in patient monitoring, especially in the case of dangerous diseases like cancer. Findings: A novel proposed structure, with reduced size, flexible substrate and good efficiency percentage was obtained with the main purpose of detecting a very small tumor. The simulation\'s results as well as the measured ones are very similar and suitable for the intended purpose. Application: In comparison with previous research, this novel proposed structure is characterized by a minimized size, good flexibility as well as with acceptable results in the gain, directivity and SAR value. But, the most important benefit is the antenna being helpful in the identification and detection of breast cancer with a minimum difference between the unhealthy and healthy breast, according to the current density results.
