Design of a Microwave Endoscopy Antenna Applicator for Early Colorectal Cancer Detection

Abstract

This paper presents an experimental microwave colon imaging system operating from 5 to 9 GHz. In comparison to traditional microwave imaging systems, supporting improved resolution in the detection of malignant tumors. A new antenna with a small dimension of 13×8.16 𝑚𝑚2 is created. The 3D surface and clearly defined borders of the compressed colon geometry make it easier for tumour detection to operate. The tumour's sites are localised inside a generated model of a colon with a thickness of 10 mm in order to illustrate the current state of research. A one-dimensional scanning system is employed for this. The preliminary findings demonstrate the viability of using portable microwave technology to identify early-stage colon cancer at high resolution.
