A compact slotted patch antenna for breast tumor detection

Abstract

A new efficient, comprehensive, and compact breast phantom measurement scheme with microstrip patch antenna is presented. The radiating element of the antenna is modified by cutting slots in both patch and ground plane for enhancing the electrical length and achieving omnidirectional radiation pattern with high gain. This methodology increases the operating frequency and as well as gain and efficiency without affecting the dimension of the antenna. The overall dimension of the antenna is 23 mm × 21 mm. The fractional bandwidth of the antenna is near about 117% (3.1–12 GHz) for −10 dB return loss with omnidirectional radiation pattern. The result shows that the average gain is 4.7 dBi with a maximum of 6.2 dBi and maximum efficiency of 98% over the operating bandwidth. The proposed prototype is simulated, fabricated, and measured, and simulated results are properly analyzed. The fidelity factor for 2 scenario of face to face and side by side also observed. Various parameters of the antenna are studied on breast phantom model with tumor sample for validating the antennas performance on breast phantom measurement. A simulation model is proposed where the antennas act as a transceiver in breast phantom measurement system for detecting undesirable tumor cells interior to the breast.

Design of a Compact CPW-Fed Monopole Antenna With Asymmetrical Hexagonal Slot Loaded Ground Structure for C/X/Ku Band Applications

“…Printing technology is developing at a rapid pace with improved antenna performance for different areas of applications. Micro strip antenna is widely preferred for RF energy harvesting [1], [2], system, medical applications [3], wireless communication [4], radio-frequency identification (RFID) [5] and smart devices [6]. Researchers are working to reduce the overall antenna size and to accommodate the multiple applications into a single unit to avoid the use of multiple devices.…”

A 16‐modified antipodal Vivaldi antenna array for microwave‐based breast tumor imaging applications

“…Numerous antennas are designed over time for breast phantom imaging, such as pyramidal horn antenna, 2 the Vivaldi antenna, [3][4][5] CPW antenna, 6 EBG antenna and metamaterials, 7 array antenna, 8 and the slotted antenna. [9][10][11][12] The main difficulty of designing an antipodal Vivaldi antenna is to get a directive radiation pattern and a lower frequency band resonance with compact dimension. From 1987, Vivaldi antenna design has given much consideration for medical applications for the identical properties that are desired for microwave imaging.…”

Wrapped ultra‐wide band radar sensor based on resistively loaded bow‐tie antenna for near zone sensing applications

“…In this regard, the impulse radar characterized by UWB pulse has widely utilized for near zone sensing applications. The applications in the vicinity of the targets can be included for not only medical applications, such as imaging of the breast tumor, imaging of the bleeding area for stroke, and assessment of bone mineral density, but also industrial applications such as ground‐penetrating radar (GPR), through‐wall penetrating radar, and foliage‐penetrating radar (FPR) …”
