Abstract:
Breast cancer is a disease that affects large population of women around the
world.Unwanted tumor cells in the breast tissue are the primary cause of breast can-
cer. Early detection and treatment can improve the survival rates.X-ray mammogra-
phy, Computed Tomography (CT), Ultra Audio (UA), Magnetic Resonance Imaging
(MRI), and Positron Emission Tomography (PET) are the conventional breast imag-
ing techniques.These approaches do have certain disadvantages, though, like their
high cost, ionisation effects, and time-consuming testing procedures.In this thesis a
microwave imaging system for detecting breast tumor is introduced.A compact flex-
ible F- slot monopole antenna is designed for Microwave Imaging (MI) of breast
cancer.The proposed antenna consists of two flexible substrate materials viz denim
and felt having dimensions 10 × 10 mm 2 and 10 × 15 mm 2 , respectively. Six meta-
material (MTM) unit cells are placed into the antenna to improve gain, directivity,
and band width. This method is innovative, low-cost and has the potential to lead
to the development of a portable device that uses an enhanced iterative approach for
breast imaging. The simulated results show that the proposed antenna achieves an
impedance bandwidth greater than 10 dB from 5.6 GHz to 56.6 GHz. The intended
antenna showed a specific absorption rate (SAR) less than 1.6 watts/KG, which is
safe for human use. The proposed antenna design can thus be used for breast imaging
applications to detect tumor.
