Antennas play a pivotal role in modern wireless communication, facilitating connections between devices through wireless mediums by transmitting and receiving radio waves. In healthcare and biomedicine, Body-Centric Wireless Communication (BCWC) has gained prominence due to advancements in miniaturized sensors, wearable electronics, and biomedical technologies. This has revolutionized the field by enabling continuous disease monitoring and treatment. Our focus is on modeling and characterizing microstrip patch antennas to identify dilated tissues within the human body. What sets our approach apart is our use of antenna modeling instead of traditional biomedical sensors for detecting these tissues. In this project we have attained the values for directivity, gain, VSWR, S-parameters and SAR values as 6.3339 dB, 2.757 dB, 1.012, -43.89 dB and 1.4572 W/Kg respectively. These results are attained in the frequency range of 2 to 2.4 GHz at the resonant frequency of 2.11 GHz. The different S-parameters for the different tissue mesh like skin, fat and tumor can help in the detection of dilated tissue.
