Microwave Sensor for Early Breast Cancer Detection

The vulnerability of women to breast cancer is evident. It is estimated that 2.3 women globally receive breast cancer diagnoses each year. The rise in its occurrence and mortality rates over the past thirty years can be attributed to shifts in risk factors and advancements in cancer detection. The current work presents a compact planar CPW-Fed sensor for breast cancer detection. The simulated and measured results demonstrate a good sensor impedance bandwidth (S11
$< -10\text{dB})$
with the operational frequency spanning from 0.8 to 1
$GHz$
. The overall size of the fabricated sensor is 120
$\times 1Z0\times 0.535mm^{3}$
. Simulations of the sensor near a breast model, both with and without a tumor, have also been carried out. Tumors of varying sizes integrated into glandular breast tissue are also tested.
