Coplanar Waveguide Fed Hexagonal Shaped Slot Antenna for Breast Tumor Detection
Journal Title: JOURNAL OF ADVANCES IN CHEMISTRY - Year 2016, Vol 12, Issue 22
Abstract
Breast cancer diagnosis is the second most mortal diseases for women in the worldwide. Recently microwave imaging has been the diagnostic techniques applied for the detection of breast cancer, heart stroke detection, brain cancer detection. A microwave imaging system requires an antenna which operates in an ultra wide band frequency range of 3.1 – 10.6 GHz and resonates at single and multiple frequencies. A novel coplanar waveguide fed micro-strip patch antenna is designed for the breast tumor detection based microwave imaging system which is the major objective presented in this paper. The design consists of coplanar waveguide fed hexagon shaped slotted patch antenna with dimension of 25x25x1mm3 and FR4 substrate of dielectric constant 4.4. Parametric analysis is performed and it provides a wide band of 2.3 GHz – 10.7 GHz and a fractional bandwidth of 129%. The design is very suitable for breast tumor detection. It provides a reflection loss of -49.8dB at 7GHz and VSWR <2 over 2.3 GHz – 10.7GHz.
