Design and Analysis of a Flexible Softwear Antenna for Tumor Detection in Skin and Breast Model

Abstract

A novel flexible softwear hexagonal patch antenna with jean substrate operating in industrial, scientific and medical band was presented. Two step methodologies are recommended. This involves the design of the proposed antenna with a hexagonal patch with a hexagon slot and without slot in which jeans substrate was introduced using HFSS and further the antenna was positioned on the skin and breast of human body model using CST. Simulated antenna results indicate the tumor detection present in skin and breast by observing the changes in the gain and current density of the skin and breast with and without tumor. An experimental set up was introduced, in which the proposed antenna was kept under various temperature and the changes in the performance of the antenna was noted and tabulated. With respect to time a change in shift of frequency was observed. With and without tumor was assumed with pieces of uniformly shaped ice cubes in the experimental analysis. In simulation the presence and absence of tumor is 20.3 A/m2 and 19 A/m2 and gain as 7.20 and 7.25 dB was noted in breast model in CST. And the existence of the tumor is 25.9 A/m2 and the nonexistence of the tumor is 21.1 A/m2 and the gain is 6.91 dB for with and without tumor is 6.95 dB is noted using CST. This technique reduces the risk of high intensity X-rays for the detection of cancer tumor by using tomography and mammography. Thus two software’s has been simulated to design an antenna and to implement it on the human model. The fabricated and measured result of the proposed softwear antenna and the experimental verification has been done.
