Cancer Diagnosis in Breast Using Biological and Electromagnetic Properties of Breast Tissues on Antenna Performance

摘要

This article is illustrating Cancer diagnosis in breast using the biological investigation and the effect of electromagnetic properties of breast tissues on antenna performance. The antenna is implanted on breast. It is made of copper annealed and implemented on FR4 substrate. It is operating on industrial, scientific, and medical (ISM) frequency band. The ground is truncated to tune the antenna in that band. The breast is modelled as three layers of skin, fat and glandular. On the other hand a model including additional lymph nodes is presented. Return loss is used as an image for studying the effect of normal and infected tissues. Different sizes and number of tumors are tackled to visualize the first stage of Cancer diagnosis. The adopted antenna is fabricated and measured on network analyzer. It is measured on free space and on normal human breast. The simulations of different structures are carried out on CST microwave studio. There is a fair agreement between the measured and simulated results. The applied scenario gives a future proposal for some element bricks to build a communication link for breast Cancer diagnosis and reduces the need for invasive surgical operations. It is also feasible to be applied in the intermediate steps during treatment.
