Tumour Detection in Fabricated Gelatin Brain Phantom Model Using Ultra Wide Band Planner Antenna

Abstract

This paper describes the design of an antenna and the development of a brain phantom model to validate the simulation results. The fabricated design of the phantom is interfaced with fabricated antenna, and the tumour in the fabricated phantom brain model is detected by return loss variation of the transmitted and reflected signals. Antennas are designed at the 2.45 GHz ISM (Industrial Science Medical) band and 5.8 GHz, and the lengths and widths for rectangular microstrip patch antenna (RMPA) have been calculated from the standard design equations. Different types of defects are applied in the front plane and ground plane of the antenna. Defect Ground Structures (DGSs) are applied to make the antenna ultra-wideband (UWB), because UWB is the basic requirement of antenna used in tumour detection applications. The design of gelatine brain phantom models with tumour and tumour-free is described. Finally, the brain phantom design is interfaced to each deigned antenna. The tumour in brain is detected by variations in the incident and reflected wave reflection loss parameter.
