This paper presents microwave imaging system simulation for brain tumor detection of human head model developed using Computer Simulation Technology software. The detection method applied by analyzing processed scattering parameter (S-parameter) signals difference in the absence and presence of tumor in head model. The simulation system covered novel design of UWB array antenna as scanning probe and human head model with tumor inside. The antenna operated from 2.6GHz until 13.1GHz, dimensions of 80 × 45 (mm) and maximum gain of 12.12dB used to scan 9 different points at the head model. Matrix Laboratory software is utilized to analyze S-parameter in frequency and time domain. The generated S-parameters of frequency domain transformed into time domain through Inverse Fast Fourier Transform for easier analysis. Smoothing ‘mslowess’ procedure is applied in filtering out the noise for accurate results. Brain tumor presence indicated by lower reflection coefficient values compared to higher values recorded by brain tumor absence.
