Being planar and having many applications 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 EM radiation are impossible. So this paper is focused on a breast model to detect the presence of tumor inside it along with antenna structure as a radiation source. HFSS simulation software is used for designing and simulation part. Antenna is resonating at 2.46 GHz in frequency range 2.41-2.5 GHz of ISM band suitable for medical purpose. Two models, one of which has microstrip patch antennas along with breast model without tumor and the other with tumor, are designed and simulated, and their radiation properties are compared. For cancer detection near E-field results are important, so near E-field plots for both models are shown in this paper. The differences in these results of two models can be used to diagnose tumor.
