M
icrowave Imaging (MI) is an emerging non-invasive
and non-ionizing technique for breast cancer
diagnosis based on microwave backscattered by breast
tissues. Dielectric properties of cancerous tissues are
considerably high compare to the normal tissues therefore
the backscattered rays of tissues analyzed and locate using
inverse image reconstruction algorithm. The motivation of
this work is early detection of breast cancer and for more
precise results with low expenses. Due to low contrast of
image by x-ray mammography, age group restriction and
false result ratio, it’s hard to say that Mammography is
beneficial or harmful. Another fact about mammography is
a painful process of analysis, therefore, we must develope
some method which is user friendly i.e., for patients. This
work presents initial results of simulation and design of a
hard and flexible antennas ranging between 0.001 GHz to
3 GHz for
in vitro
experimentation. Basically the Microstrip
Patch antennas of two different shapes were simulated and
fabricated in this first step with different materials like FR4,
Cotton cloth, Polyester and Kapton Polyimide (for Flexible
antennas). The size of antenna depends on permittivity of
substrate material and resonance frequency. To analyze
the design and scattering parameters of antennas High
Frequency Simulation Software (HFSS) used for different
materials of substrate. Antennas are tested using mimic-
phantoms of breast. The simulation results of rectangular
patch and circular slot antennas show a peak of microwave
emission / detection at 2 GHz and 300 MHz band width
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.
