An Off-Diagonal Feed Elliptical Patch Antenna With Ring Shaped Slot in Ground Plane for Microwave Imaging of Breast

Being having many advantages of microstrip patch antennas, nowadays these also have applications in biomedical field (for detection of cancer). As EM radiations are hazardous so direct experiments on human body and electromagnetic radiation is impossible. So this paper focused on a breast model to detect the presence of tumor inside it along with antenna structure as radiating source. HFSS simulation software is used for designing and simulation part. Antenna is resonating at 2.46GHz in frequency range (2.41-2.5 GHz) of ISM band suitable for medical purpose. Two models one having microstrip patch antennas along with breast model without tumor and other with tumor are designed simulated and their radiation properties are compared. For cancer detection near Efield results are important so near E-field plot for the two models are shown in this paper. The differences in these results of two models can be used to diagnose tumor.
