摘要

Breast cancer is the most prevalent type of cancer in women overall. Out of an estimated 2.3 million new cases worldwide in 2022, 670,000 women died from breast cancer. Around the world, one woman is diagnosed with breast cancer every fourteen seconds. Many lives are saved when cancer cells are discovered early. This work explores the novel octuplet-shaped Terahertz (THz) patch antenna for tumor detection in a breast phantom. The investigation started with octuplet antenna characteristics with various design steps using the CST tool. Further, the breast phantom is modeled with the proposed octuplet patch structure and analyze the performances. The breast model is classified into four quadrants and the tumor is placed in the different quadrants. Based on the antenna characteristics, the location of the tumor is detected. Also, the tumor size is optimized for various sizes and compare the performance. The suggested octuplet patch antenna (OPA) resonated in the THz frequency range, which is safer and has no effect on human health because it lacks ionizing properties. Particularly in places with limited resources, the patch structure that has been proposed is small, less costly, lightweight, environmentally safe, and can be used as the primary method of screening for breast cancer.
