“…Antenna in the radar based MWI system should has compact size, directive radiation pattern, linear phase response, flat group delay and ultra-wide bandwidth. For high resolution images, antennas must send short duration, narrow pulse signal which depends on bandwidth [8]. After Federal Communication Commission (FCC) allowed unlicensed use of operating bandwidth from 3.1 GHz to 10.6 GHz in 2002, UWB antennas for the radar applications have attracted great attention of researchers.…”

In this study, a novel ultra-wide band (UWB) antipodal Vivaldi antenna with three pairs of slots designed to be used as a sensor in microwave imaging (MWI) system for breast cancer detection. The proposed antenna operates in UWB frequency range of 3.05-12.2 GHz. FR4 was used as a dielectric material and as a substrate for forming the antenna that has a compact size of 36 mm x 36 mm x 1.6 mm. Frequency and time domain performance of the proposed antenna have been investigated and results show that it meets the requirements for UWB radar applications with linear phase response, nearly constant group delay, ultra-wide bandwidth and directional properties at most of the operating frequency. Then, the capacity of the proposed antenna as a sensor was tested in a monostatic microwave breast imaging system that was developed in the CST Microwave Studio (CST MWS) simulation software. In the simulation application, 50 mm radius hemi-sphreical breast models with different densities were formed and 2 mm diameter spherical tumor was placed inside them. Antennas were positioned cylindrically around the breast to send Gaussian pulse and collect backscattered signals. After signal processing steps, tumors was screened at correct positions with high resolution. Finally, a monostatic radar based breast phantom measurement system developed to automatically scan the breast phantom in the prone position. To perform experimental measurements, an electrically and anatomically realistic homogeneous breast phantom with tumor inside was fabricated. Screening of the tumor at correct location indicates that the proposed antenna and the microwave imaging system developed using this antenna are suitable for the detection of breast cancer at the early stage.
