Abstract

This project is to design the antenna array for the use of ultra wide band frequency range spectrum.In the ultra wide band frequency,the microwave imaging has been used to detect the unusual tissues in the human body for example a tumor cell,cancer cell and other cells which uncompatible with normal tissue in human body.In addition,the microwave imaging also can provide an accurate detection and a good treatment with low cost for the early detection.The main thing about the microwave imaging technique is to observe microwave frequencies and conductivity between the normal and the malignant tissues.Therefore,an antenna was designed in an array design by using a suitable substrate in order to detect the unusual tissue in the human body.A substrate called Rogers RT/Duroid 5880 was used in this project as the thickness is just about 1.575mm which can easily flexible to all type of parts in the human body shapes.The antenna was designed by using a Computer Simulation Software (CST) to achieve a simulation result.The ultra wide band frequency for unusual tissue detection for microwave imaging is between the range of 3.1 GHz to 10.6 GHz.However,after done doing the simulation test,the result obtained was between the range of 3.5942 GHz until 8.1836 GHz with a bandwidth of 4.5894.While,for the two lowest return loss shows the simulation result of -17.594 and -16.724 with frequencies of 4.4750 GHz and 7.0565 GHz respectively.A lots of parameter sweep already done to make sure that the frequency of the antenna is between the bandwidth of the ultra wide band frequency range spectrum. Therefore,this antenna is practical used in the medical sector which helps the doctors and nurses applied this technology to the patients s ince the structure is flexible to all type of body shapes and the resulting frequency is still in the range of reading frequency microwave imaging.
