Abstract
This paper presents a microstrip patch antenna working at MICS (Medical Implant Communication System) band whose core band is 402–405 MHz for the detection of tumor in human breast tissue. The proposed antenna is designed and fabricated on the FR-4 substrate with dielectric constant 4.4, thickness 1.6 mm and loss tangent 0.0024. The actual antenna size is 15 mm × 15 mm which is small enough to be implanted in breast tissue to give satisfactory performance. To analyze the characteristics of antenna, it is embedded in the gel type tissue material whose electrical properties are the same as that of the human skin in case of conductivity and permittivity. MICS band is preferred because of its docility towards higher bandwidth. There is a difference in return loss characteristic of the antenna which has been simulated with and without tumor. This difference in return loss clearly depicts the presence of tumor inside the breast. Various parameters such as return loss, radiation pattern and directivity are also measured for the proposed antenna at 402–405 MHz band.
