Abstract
Breast cancer has in recent time become a leading cause of mortality among women, which necessitate a suitable means of early detection for fast and effective treatment. X-ray Mammography, which is currently the commonly used method of breast screening, comes with limitations such as missed detection because of poor malignant/benign cancer tissue contrast as well as exposure of the breast to radiation. Microwave imaging serves as a better alternative to X-ray mammography, because of its harmlessness to humans and better detection. In this paper, a study on the effects of the bending of the microstrip antenna array for breast tumour detection is presented. The antenna array was designed with resonant frequencies of 2.4 GHz and return loss less than -35 dB. The antenna is simulated by introducing a truncated edge slot at the network feedline of the conformal antenna array. The result shows that the proposed antenna design is capable of detecting the breast tumour with improved characteristics compared to other designs available in the literature. The simulation analysis of the designed antenna is carried out using CST software. The capabilities and bending effect of this antenna for detecting different tumour sizes is investigated and its potential is highlighted. The results obtained with this antenna design makes it suitable antenna for breast tumour detection
