1×2 Pentagonal Patch Antenna Array Based Pancreatic Cancer Detection
2024 IEEE APPLIED SENSING CONFERENCE, APSCON(2024)
Abstract
This paper introduces a microwave technique to diagnose pancreatic cancer (PC) through a 1x2 pentagonal patch antenna array. A pancreatic phantom consisting of pancreas, liver, kidney, spleen, adrenal glands, gall bladder, ureter, muscle, fat, and skin is used with the antenna array. The operating band of the array lies within the frequency range of 2.13-2.21 GHz. The PC is studied by the introduction of a tumor in the phantom model of a healthy pancreas. It is observed that the tumor causes a shift in the resonance frequency of the antenna. The parameters of the antenna array are studied without and with tumor. A tumor's presence results in an enhancement in reflection (VSWR), and an increase in E-field and gain of the antenna array. The Specific absorption rate (SAR) is below 2 W/Kg (for 10g), which is well within the safety limits. The current work provides a simple PC diagnosis technique that is fast, safe, compact, economical, comfortable, and non-invasive.
