“…In 2007, Klemm et al optimized a symmetrically curved antenna array, and at the same time, the realistic 3D curved breast phantom with appropriate electrical properties is used [38]. Unlike the earlier prototype shown in Figure 3(b), in the symmetrically curved antenna array (second-generation), the antennas were aligned in rows and columns, and the array has two axes of symmetry as shown in Figure 5(a).…”

Abstract-In the last decades, microwave imaging has been a new area of research due to its many advantages over current imaging systems. Microwave imaging system is used for in-depth inspection of biological tissues. The test provides the identification of morphological changes in these biological tissues, as well as their locations. The emerging Ultra-Wideband (UWB) microwave imaging gives better result with the main advantage of using non-ionizing radiation. In these systems, antennas play a very important role, and as such, their optimization has become a very important topic because the device is placed close to the human body. Thus, many aspects are of great importance in the design of the antennas starting from the material with which it is constructed, its dimensions, operation bandwidth, human body influence on the antenna parameters, short-pulse propagation, etc. Recent research has shown several efforts in improving the electromagnetic sensors used in these systems, either as individual or array elements. In this paper, we provide an overview of the most relevant developments in the field of UWB high directivity sensors used in microwave imaging systems.

“…A large variety of experimental techniques can be used to measure the dielectric constant of materials, including human and animal tissues at different microwave frequencies [89][90][91][92][93]. These techniques do not directly measure the permittivity, but this can be inferred from the measured data of variables such as impedance, reflectivity and the transmission losses which are dependent on it.…”

A microwave medical imaging system processes scattered electromagnetic fields in the microwave region to create images. It is an alternative or complementary imaging tool that can be used in medical applications to assist the diagnosis of disease inside the human body. For example, microwave imaging offers many desirable characteristics as a cancer evaluation tool. It is a non-ionising radiation and during measurement, compression of the scanned body part is avoided. These benefits potentially lead to safer and more comfortable examinations. It also has the potential to be both sensitive and specific to detect small tumors, whilst being much lower cost than current methods, such as magnetic resonant imaging, positron emission tomography and ultrasound. However, it should be noted that all current imaging modalities have a relatively high incidence of false positive and false negative results. Moreover, microwave medical imaging designs can be made portable, so real time results for applications such as brain stroke detection is feasible.This thesis proposes several microwave medical imaging systems based on ultrawideband technology and in doing so makes five contributions to the field of microwave imaging systems. The first contribution is the development of a UWB slotted Vivaldi antenna that operates as the transducer for imaging systems. The antenna is compact structure to overcome the shortcoming of conventional Vivaldi tapered-slot antennas. The antennas have a stable main-beam direction and high dynamic range. They are designed to work efficiently in a coupling medium. The designed antennas provide high sensitivity and excellent time-domain characteristics to enhance the capability of the proposed imaging systems.The second contribution of the thesis is the development of coupling medium and artificial phantoms that emulate the electrical properties of realistic tissue in order to test and assess the proposed microwave imaging systems before application to human subject.Two types of coupling medium are described. A breast phantom and a head phantom are designed and fabricated. The materials of the fabricated phantoms mimic the electromagnetic features of realistic human tissues. The electrical characteristics of all the fabricated materials show excellent matching when compared with the available data on real human tissue.The third contribution of the thesis is the design of a microwave medical imaging system for breast cancer detection. A planar scanning system is developed. The laboratory assessment of a two-dimensional and three-dimensional imaged breast phantom is iii explained. An experimental study of the breast cancer detection employing a fabricated semi-rectangular shaped phantom is conducted. An image reconstruction algorithm is developed to generate the images of the breast phantom using the measurement data.The results show the ability of the designed microwave imaging system to detect and localise tumors at different locations of the breast phantom.The fourth contribution of the thesis ...
