Vivaldi antenna and breast phantom design for breast cancer imaging

In this work, the design and implementation of a Vivaldi antenna (BAVA) and breast phantom for breast cancer imaging have been covered within the range of 3.1-10.6 GHz. A good impedance matching between simulation and measurements is presented here. Two different phantoms are made to simulate the scene. A dielectric constant relatively close to the real breast tissues has also been found. This design has the ability to be used in breast cancer detection without the need of any liquid coupling medium which is required in many other publications.
