It can also be usable in microwave imaging technology for breast cancer tumor detection. Our research presents the design and performance analysis of an UWB micro strip patch antenna. By using jeans cloth as substrate material the flexibility of the antenna structure has increased. The antenna bandwidth also increased for the dielectric properties of the substrate. 3.5 GHz to 20 GHz of operating frequency range is gained with minimum -35 dB return loss at 5.5GHz and - 45dB at 14.04GHz. The total bandwidth obtained is 18.5 GHz which is comparatively high with an efficiency of around (75-80) % .The UWB and cloth material substrate makes it preferable for using in breast cancer detection equipment.enThesis
