Simulasi Perancangan Antena Array Ultra Wideband (Uwb) Dengan Metode Defected Ground Structure (Dgs) Berbentuk Bee Comb Untuk Keperluan Sistem Pendeteksian Tumor Pada Otak
ABSTRACT
Cancer and brain tumors are very serious diseases and problems for human health. Early detection of brain tumors is indispensable considering that every year the victims are increasing. Ultra Wideband microwave imaging is a technique that uses electromagnetic signals with wide bandwidth to see through the internal structure of the brain. This study introduces a circular and rectangular array antenna design in a circle configuration that operates in frequency range from 2 GHz to 12 GHz, the antennas are designed and simulated to detect the presence of tumors. The analysis was carried out by comparing E-Field and the number of Specific Absorption Rate (SAR) with tumors. With a circle configuration, each antenna element faces directly into brain phantom for better tumor detection. From the simulation results, E-Field and SAR are obtained in the brain with tumors. The SAR obtained is around 0.493 W / Kg.
