| dc.description.abstract | This study aimed to design a printed UWB antenna, specifically for breast cancer detection. Breast cancer has been the most common invasive cancer in females worldwide and ranked high as the most dangerous cancer that can cause death. Although there are multiple common techniques to detect breast cancer such as X-ray mammography and Magnetic Resonance Imaging (MRI), those techniques still have limitations and drawbacks. This project focuses in detecting the tumour in breast via microwave imaging. In this study, UWB antenna with a compact size of 16 mm x 16 mm, P-shaped slot design has been developed. The antenna was optimized for operation from 2.93 GHz to 6.85 GHz. The antenna has the peak gain of 3.11 dB and has the maximum radiation intensity at higher gain. The UWB antennas were placed on different tested mediums with different dielectric properties to detect the region of significant of dielectric constant. The Vector Network Analyser (VNA) is used to obtain the magnitude of signal from each of pairing antennas and the image is reconstructed, representing the tumour’s size and location. MATLAB is used to reconstruct the image obtained into better image for more valuable information. The performance of the antennas designed are analysed. | en_US |
