Enhanced Accuracy of Breast Cancer Detection Based on UWB Compact Slotted Monopole Antennas

Abstract

This work presents a new breast tumor detection system based on an omnidirectional microstrip ultra wideband antenna. The localization coordinates of the tumor are studied in detail for better tumor detection. The coordinates of the corresponding maximum value of SAR are identified in order to accurately detect different locations of tumor inside the breast. The results show that relying on these coordinates; the tumor can be detected with high accuracy. The possibility of mutual interferences with other systems operating at the FCC frequency band is considered as a major issue in UWB systems. Therefore, rejected out-band interference signals is introduced by etching single and double U-shaped slots on the radiating element, then a first and second frequency band are successfully produced respectively. The proposed antenna is a compact antenna that can be used on microwave imaging detection. The antenna gain was larger than 2 dbi with an omnidirectional radiation pattern over the whole frequency-band. A relatively flat group delay of the antenna response is also achieved. Antenna prototype has been manufactured and measured, results prove the performance of the proposed antenna.

A curved single‐layer FSS design for gain improvement of a compact size CPW‐fed UWB monopole antenna

“…11,12 Diverse geometries of slots have been incorporated in the radiating elements, which considerably improves the impedance bandwidth of these antennas. 13 For particular applications, such as antenna radomes, microwave imaging detection systems, radar cross section (RCS) control, and ground-penetrating radar (GPR), to improve the precision and detection distance, it is imperative to utilize ultra-wideband (UWB) antennas that possess high gain and directivity, 14,15 and these characteristics can be improved using various approaches, including artificial magnetic conductors (AMCs), 16 reactive impedance surfaces (RISs), 17 the employment of antenna arrays, 18 and frequency selective surfaces (FSSs). 19 Remarkably, FSS keeps pace with the evolving requirements for more expanded bandwidth for wireless communication objectives and some other advanced functionalities that lean on a specific bandwidth to execute.…”

A Novel Approach of a Low-Cost UWB Microwave Imaging System with High Resolution Based on SAR and a New Fast Reconstruction Algorithm for Early-Stage Breast Cancer Detection

“…X-ray mammography is currently the gold-standard method for breast cancer detection. However, it has the disadvantages of harmful radiation, uncomfortable compression of the breast during examination, and relatively high false-negative rates [ 1 , 2 ]. Recently, confocal microwave imaging has attracted the interest of a number of research groups as an effective alternative.…”

Multislot Rectangular Microstrip Patch Antenna Design to Detect Breast Cancer

“…In 2020, there are over 2.3 million new cases reported according to World Health Organization (WHO). However, early diagnosis reduces death and increases survival chances (2). A variety of screening methods are commonly used to detect breast cancer, including X-ray mammography, computed tomography (CT) scans, Ultra-Sonic imaging (US), and magnetic resonance imaging (MRI).…”
