Abstract :

The detection of kidney cancer at early stages plays a pivotal role in improving patient survival rates. This study presents the design and simulation of a microstrip patch antenna aimed at enhancing non-invasive cancer detection. The antenna operates in the microwave frequency range suitable for distinguishing malignant from healthy tissues based on dielectric contrasts. A rectangular patch geometry with optimized dimensions was developed using electromagnetic simulation tools. The proposed antenna demonstrates high gain, adequate bandwidth, and stable radiation characteristics. Numerical phantom models of kidney tissue were used for validation. The design shows potential for integration into microwave imaging systems. Results indicate promising sensitivity for detecting abnormal tissue regions. The antenna’s performance is evaluated against existing designs. This work contributes to advancing biomedical microwave diagnostics.
