CMI for breast cancer detection was originally developed based on several assumptions regarding the dielectric properties of normal andIn this paper, a novel imaging algorithm is described, which uses a rotating antenna system to increase the number of unique propagation paths to and from the...
Simulation Design and Testing of a Dielectric Embedded Some of these attempts were for a TSA enclosed in a dielectric rod for gain improvement in communications and radar systems [8]. For microwave breast cancer detection systems, a balanced antipodal Vivaldi antenna was designed with a profiled higher dielectric constant material to increase the antenna directivity [9].
In this paper, a miniaturized coplanar waveguide fed (CPW-fed) tapered slot antenna (TSA) is introduced for breast cancer detection. Here, a modified CPW to slot-line transition structure with an air-bridge is employed to broaden the transition bandwidth and increase the radiation efficiency. Through these applied modifications, negative features of the original TSA (limitation of transition ...
A Comparison of a Wide-Slot and a Stacked Patch Antenna ... The compact nature of the slot antenna means that the detection array can be densely populated. Additionally, this new antenna offers better radiation coverage of the breast. For angles up to 60° away from bore-sight radiated pulses are almost identical (fidelity >95%), whereas for the patch antenna fidelity falls to 58% at the angular extremes.

INTRODUCTION According to cancer incidence statics in 2012, 14.1 million people were diagnosed with cancer world wide and 8,2 million people died from cancer [1]. Over 100,000 new breast cancer patients are diagnosed annually in India. As per the ICMR-PBCR data ...
technology is breast cancer detection through imaging [2,3]. Breast cancer is a very dangerous and deadly disease and an early detection of smaller tumors have a better chance of successful treatment [4]. Because of their wide bandwidth and high gain, tapered slot antennas (TSAs) have been utilized in breast cancer detection [5,6].
Novel Antenna Structure for Early Breast Cancer Detection ... From a sensing-method point of view, radiometers present an ideal solution for early breast cancer detection because of their inherent passive, and in effect, non-invasive operation. In other words, no energy is injected into the body while making measurements, and thus, any fear of electromagnetic radiation effects on the body is nullified. International Journal of Antennas and Propagation - Hindawi A novel planar type antenna printed on a high permittivity Rogers’ substrate is proposed for early stage microwave breast cancer detection. The design is based on a p-shaped wide-slot structure with microstrip feeding circuit to eliminate losses of transmission. The design parameters are optimized resulting in a good reflection coefficient at −10 dB from 4.5 to 10.9 GHz. UWB Microwave Breast Cancer Detection Using SAR (UWB), microwave detection, breast cancer. I. INTRODUCTION Breast cancer is the most common cancer in women. In 2012, an estimated 22,900 cases of breast cancer were diagnosed in the United States and Canada with as many as 5,200 cases leading to death. For women, breast cancer mortality rates are higher than for
