Abstract:
“Design of UWB Circular Antenna Array System for Microwave Imaging Radar’’ is proposed in this report. The proposed antenna is structured for detection of cancerous cells in women breast. An array of 1x4 elements is designed, fabricated, and evaluated for the detection and diagnosis of the breast cancer tumor. The frequency range of the operation of the array is from 3.4 to 11 GHz. The return loss of the array is found to be less than -12 dB throughout the frequency band of operation 3.4 -11 GHz. Microwave Imaging techniques have used of the detection of breast cancer with the proposed antenna. The phantom developed by our colleague at MCS is tested using the same array over the complete frequency band and remarkably interesting results have been achieved. Similarly, the tumor in phantom has also been tested by the single element as well as using the developed array and very favorable results have been achieved throughout the band of operation from 3.4 -11 GHz.
