Design of ultra-wideband microwave circular array of multi ring slots shape patch antenna for detection breast cancer tumors

Microwave imaging (MI) techniques have been used for early detection of breast cancer that affects most women as an alternative to X-rays. Therefore, the location and size of the breast tumor must be precisely determined in its advanced stages. An antenna has been designed in the form of multi ring...

Description
Summary:Microwave imaging (MI) techniques have been used for early detection of breast cancer that affects most women as an alternative to X-rays. Therefore, the location and size of the breast tumor must be precisely determined in its advanced stages. An antenna has been designed in the form of multi ring (Fractal antenna) ultra-wide band, and after simulating it, it was designed in the form of an array consisting of fourteen antennas around the breast and this array works at frequencies between (3.439-4.932) GHz and (5.334-6.311) GHz and (6.763 to over 12) GHz at S11 less than - 10dB. It has a resonant frequency of 8.571 GHz at a return loss of -56.855 dB and a SAR value of 1.4 W / kg. This antenna, circular array of antennas and breast phantom are stimulated by CST program 2014.
