“…Afterwards, the controlling device triggered the VNA to start the measurement of the backscattering (S) parameters (S11, S21, S12 and S22) over the entire operating band and transmitted from the VNA to the PC by using the GPIB port. Subsequently, data were processed using the Delay-Multiply-and–Sum (DMAS) algorithm14 to reconstruct the image in the frequency domain, and an inverse discrete Fourier transform…”

In this paper, we report a compact and ultra-wide band antenna on a flexible substrate using the 5-(4-(perfluorohexyl)phenyl)thiophene-2-carbaldehyde compound for microwave imaging. In contrast to other microwave based imaging systems, such as an array of 16 antennas, we proposed a bi-static radar based imaging system consisting of two omnidirectional antennas, which reduces complexity and the overall dimension. The proposed compact antennas are 20 × 14 mm2 and designed for operating at frequencies from 4 to 6 GHz. To allow for implantation into a bra, the electromagnetic performances of the antennas must be considered in bending conditions. In comparison with the recently reported flexible antennas, we demonstrated both electromagnetic performance and imaging reconstruction for bending conditions. For the proof of concept, the electromagnetic performances both at flat and bending conditions have been verified using a homogeneous multilayer model of the human breast phantom. Our results demonstrate that the antenna, even at bending conditions, exhibits an excellent omni-directional radiation pattern with an average efficiency above 70% and average gain above 1 dBi, within the operational frequency band. The comprehensive aim of the realized antenna is to design a biodegradable and wearable antenna-based bra for early breast cancer detection in the future.

“…This kind of substrate allows the elements to take the shape of the breast, maintaining adequate coverage over the area under study between 2 and 5 GHz. Adding reflectors behind the array improves the power gain and the ability to detect the presence of tumor [47]. The mentioned findings were the basis for the design shown on Figure 13.…”

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.

Abstract-A compact Ultra Wideband (UWB) antenna with Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Local Area Network (WLAN) with dual-band notched characteristics is presented in this article. The antenna design parameters have been optimized by the High Frequency Structural Simulator (HFSS) and CST Microwave Studio to be in contact with biological breast tissues over 3-13 GHz frequency range with dual band-notched characteristics. The proposed antenna is a polygon printed on a low dielectric FR4 substrate fed by a 50-Ω feed line and a partial ground plane in other side. The results exhibit that the proposed antenna shows a wide bandwidth covering from 3 GHz to at least 13 GHz with VSWR < 2 and observing band elimination of WiMAX and WLAN bands. The proposed UWB antenna has omnidirectional radiation patterns with a gain variation of 0.5 dBi to 5.2 dBi and low distortion group delay less than 1 ns over the operating frequency range. The simulation and measurement results show a good agreement. And good ultra-wideband linear transmission performance has been achieved in time domain with a compact dimension of 28 × 20 mm 2 .
