-rays Mammography is a gold-standard for breast cancer

detection. Mammography has many shortcomes like

painful screening, false results, need biopsy for results

verification etc. Microwave Imaging (MWI) emerges as a

painless alternative technique for breast screening. MWI

works on the principle of reconstruction of image using

inverse scattering radiation from spatial distribution of

dielectric properties of breast tissues. In the present work,

flexible rectangular split antenna, with pyralux polyimide

substrate and 41x23 mm2 in size, were simulated and

characterized the presence of a breast phantom. The

phantom has the dielectric properties of normal breast

tissues and malignant tumors. The resonance frequency of

antenna is 2.2 GHz, which is in compliance with the suitable

frequency range for breast cancer imaging fromthe literature.

Results shows that the electric field distribution is maximum

at around the tumor tissue which is about 350V/m, whereas

in healthy tissue the maximum electric field is 139V/m and

for skin tissues is 103V/m. The electric field is directly related

to the specific absorption rate (SAR) of radiations which is

also higher for tumor tissue with respect to normal.

Speaker Biography

Maryam Liaqat did her Master’s in Physics in 2013 from University of Agriculture,

Pakistan. Currently, she is perusing PhD in Electrical Engineering from Federal

University of Pernambuco, Brazil. She is working on project of microwave antenna

modifications for the detection of breast cancer. Designing flexible antennas for

microwave imaging system, which will be user friendly, cost effective and more precise

in results as compared to x-ray mammography.
