Ultra-Wideband Flexible and Wearable Textile Antenna for Predicting Breast Cancer

It is estimated that one after 22 women in India will get breast Cancer in their life time. The possibilities of early detection are that, it will categorize cancer while still localized and curable, precluding not only mortality, but also reducing sickness and charges spend by them. Hence by developing an automated system for detecting the presence of cancerous tissue, analyzing the location and size of the developed dead tissue with low cost can support doctors for accurate diagnosis. The objective of this work is to design an Ultra-Wideband Textile Antenna in denim substrate of 0.75mm thickness with a dielectric constant of 1.7 for transmitting and receiving electromagnetic signals at 2.4GHz which can able to detect malignant tumor in breast cells. A breast tissue is placed between two Ultra-Wideband Wearable Textile Antenna and these two antenna act as sensors and we can basically characterize any biological tissue in terms of electrical features such as permittivity and tangent loss. Basically Biological tissue is highly non-homogenous material and is a mixture of blood fat and many other biological components having different permittivity and tangent loses but effectively and locally we can model this breast tissue by using a single permittivity and tangent loss which is basically a homogenous modelling at a particular frequency due to the presence of a tumor cell that homogeneity of the breast tissue will be hampered and these change of this variation of the electrical material property of the breast tissue will be captured into the transmission coefficient plot. Since this is a two port network, we can model this entire system by using a scattering matrix because we have two parts and four elements in this matrix and will be concerned mostly with the transmission coefficient and if we plot transmission coefficient versus frequency then we might have different responses depending on the tumor size, and the tumor location. So by having multiple plots, we can establish a correlation between transmission coefficient with tumor cell size and location.
