“…Moreover, their radiation performance can be improved with some changes in their geometrical properties. There are many Vivaldi antennas available in the literature that were designed with different techniques to be used in MWI breast cancer detection systems [11][12][13][14][15][16][17][18][19][20][21][22][23][24]. A compact antipodal Vivaldi antenna that operates as UWB reported in [11] but its gain is below 4 dB nearly at all operating frequencies and group delay has discontinuities at some frequencies.…”

“…Also, lower frequency band is above 3.1 GHz. In [23], slots on the fins of the antenna and parasitic elliptical patch were used in order to obtain more directive radiation pattern and more gain at lower frequency band. Operating frequency band of the antenna is between 2.5-11 GHz and maximum gain of the antenna is 7.2 dB.…”

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.

“…With respect to microwave imaging features, scholars have been proposed numerous categories of antenna for head imaging platforms. For instance, tapered slot antenna [7], triangle patch microstrip antenna [16], ultrawideband (UWB) slot antenna [17], electromagnetic band gap (EBG) based antenna [18], slotted T-shaped antenna [19], printed monopole [20], flexible monopole [6], different types of UWB array antenna [21][22][23], directional monopole antenna [6], various categories of antipodal Vivaldi antenna [24][25][26][27], various categories Vivaldi antennas [28,29], wideband textile antenna [30], conformal antenna [31], bowtie antenna [32], wideband monopole antenna [33], different types of 3D antenna such as slot-loaded wideband antenna [14], stacked 3D folded antennas [34,35], slot-loaded folded dipole antenna [36]. In the current microwave head imaging applications stage, it is essential to design comparatively small size antennas with wideband, high gain, directional radiation capability, higher bandwidth, and efficiency.…”

“…The antenna size is large with poor gain. The authors in [24][25][26][27] proposed Vivaldi antennas which are operating in between 3.0 GHz to 10.0 GHz to identify the tumor. However, because of deficiency of penetration strength, only tumor situated close to the skull/bone could be effectively identified.…”

“…It is remarkable that the antennas should be compact in dimension with superior gain, wider bandwidth as well as higher efficiency for an effective MWI system with better image quality and dynamic range. Until now, for MWI applications, a number of different categories of UWB antennas have been reported proposed in different aspects such as [9,10] (i) narrow bands versus wide bands, (ii) omnidirectional versus directional radiation patterns, (iii) low frequency versus high frequency, (iv) lower energy consumption versus capability to penetrate objects, (v) less significant electromagnetic radiation, and (vi) upper precision range.With respect to the mentioned aspects, researchers have proposed a number of Ultrawideband antennas; for example, parasitic resonator-based antennas [9,[11][12][13], differential Ultrawideband antennas [13], slotted UWB antennas [14], UWB elliptical antennas [15], sensor-based UWB [16], different types of directional UWB antennas [17][18][19][20], uniplanar metamaterial-based UWB antennas [21,22], various categories of Vivaldi antennas [23][24][25][26][27][28][29], several types of UWB monopole antennas [30][31][32], CPW-fed UWB antennas [33], tapered slot UWB [34] antennas, and numerous others. In the previous decade, UWB antennas have inaugurated to be castoff for MWI applications.…”

An Ultrawideband (UWB) octagonal ring-shaped parasitic resonator-based patch antenna for microwave imaging applications is presented in this study, which is constructed with a diamond-shaped radiating patch, three octagonal, rectangular slotted ring-shaped parasitic resonator elements, and partial slotting ground plane. The main goals of uses of parasitic ring-shaped elements are improving antenna performance. In the prototype, various kinds of slots on the ground plane were investigated, and especially rectangular slots and irregular zigzag slots are applied to enhance bandwidth, gain, efficiency, and radiation directivity. The optimized size of the antenna is 29 × 24 × 1.5 mm 3 by using the FR-4 substrate. The overall results illustrate that the antenna has a bandwidth of 8.7 GHz (2.80-11.50 GHz) for the reflection coefficient S 11 < −10 dB with directional radiation pattern. The maximum gain of the proposed prototype is more than 5.7 dBi, and the average efficiency over the radiating bandwidth is 75%. Different design modifications are performed to attain the most favorable outcome of the proposed antenna. However, the prototype of the proposed antenna is designed and simulated in the 3D simulator CST Microwave Studio 2018 and then effectively fabricated and measured. The investigation throughout the study of the numerical as well as experimental data explicit that the proposed antenna is appropriate for the Ultrawideband-based microwave-imaging fields.Sensors 2020, 20, 1354 2 of 20 technicians [6]. Therefore, it is indispensable to develop a novel imaging method to detect cancer, tumor, etc. in the human body without harmful. Last few decades, the alternative technique that is MWI has been recommended as safe to prevailing medical imaging techniques together with mammography, X-ray, ultrasound, and MRI [7]. MWI is an innovative technique, which fascinates enormous interest in medical diagnostic areas, for instance, breast tumor detection, brain tumor detection, early-stage heart failure recognition, health observing, etc. due to its low cost, low profile, portability, and non-ionizing effects. In this methodology, antenna plays a major role as well as acts as a transceiver, in which the transmitting antenna propagates the microwaves and then microwaves travel through the human body. After that, data are composed of the receiving antenna. When microwave signals scattered from dissimilar tissue of the human body, it is possible to distinguish by MWI antenna sensors. In this domain, the radiated and scattered energy is received by the antenna sensor(s) for further processing.The prime working procedure of MWI is to analyze the variance among the electrical characteristics of healthy tissue as well as malignant cells (e.g., breast tumor, brain tumor, etc.) of the human body. In a human body, the fluid of each organic tissue differs, which reasons diverse electrical characteristics. Additionally, the existence of ions, as well as free radicals in the malignant tissues, increases the dielectric loss gradually. Cons...
