An UWB Antenna Array for Breast Cancer Detection

Abstract: The aim of the thesis is to design an UWB antenna array that consist several antennas working in the frequency range from (5-10) GHz. A planar monopole antenna is being designed and investigated. Then the array of ultra wideband directive performance is being presented. This biomedical application is a classical approach for non destructive evaluation and belongs to Microwave tomography system. The antenna is being designed to work properly across the given ultra wideband frequency range from 5 GHz to 10 GHz. The antenna have very compact size (area of 9 mm ' 10.5 mm) and is immersed to liquid of high dielectric constant for breast tissue to be improved and increase the dynamic range of the system. The time domain performance of the antenna is to show the negligible distortion so that can make it perform better for medical imaging systems. Due to the better performance of the antenna the effect of the multilayer breast tissue is also investigated by calculating the fidelity factor across all the tissue layers. Now for better performance and to meet the requirements a Planar Monopole Antenna (PMA) is designed and optimized regarding to different parameters. A „‟slot also been introduced to the design to find the better result. The simulated result shows the reflection coefficients of designed antenna is <-10dB over the entire frequency band of interest (5 GHz-10GHz).
