Performance analysis of compact ultra wide band micro strip patch antenna for breast cancer detection

Abstract

Breast cancer has now surpassed lung cancer as the most commonly newlinediagnosed cancer in the world. In 2020, an estimated 2,261,419 new cases of newlinebreast cancer were diagnosed in women worldwide. The severity of breast newlinecancer can be reduced if diagnosed early and treated properly. Microwave newlineimaging research has seen a resurgence in the medical field, particularly in the newlinediagnosis of breast cancer, due to its many advantages over the existing newlineimaging techniques including computed tomography, x-rays, MRI, and newlinemammography. It aids in the location and identification of morphological newlineeffects in these tissues. Recent years have seen a significant increase in the newlineuse of the radiation-free, high-resolution, and cost-effective Ultra-Wide Band newline(UWB) microwave imaging approach for the early diagnosis of breast newlinecancers. The effectiveness of the UWB imaging approach lies in the early newlinediagnosis of breast lesions with a diameter less than 50 mm beneath the breast newlinetissue. In the microwave imaging techniques, the antenna plays a very newlineimportant role in collecting the microwave signals from the breast and hence newlinethe antenna design is significant in the breast cancer detection techniques. newlineThe main objective of this research relates to the development of newlineappropriate antenna for breast cancer detection. Various shapes of antenna newlinewere created and simulated in the ADS environment. Of all the antenna newlineshapes designed, the performance of the spanner-shaped antenna was seen as newlinesatisfactory with return loss and efficiency of -13 dB and 85.49 % newlinerespectively compared to the rectangular-shaped antennas with -14 dB return newlineloss and 62.6% efficiency. newline
