Detection of lung cancer using ultra wide band antenna

The paper presents analysis, design and implementation of cupcake ultra-wide band antenna for lung cancer detection. The antenna is fabricated on Rogers RO4350 (lossy) material of relative permittivity 3.66 and substrate layer of thickness 1.524 mm. A lung model is presented comprising the lung tissues, pleura, muscles, fats and the skin. The antenna is simulated on CST microwave studio. There is a different image of the return loss for antenna placed on normal tissues and infected tissues (with tumors).
