ANALYZING PERFORMANCE OF MICROSTRIP PATCH ANTENNA FOR DETECTING THE TUMOR IN THE HUMAN BODY
Sonam Gour, Amit Rathi
Abstract
The paper discussed the applicability of the Microstrip Patch Antenna for detecting the tumor in the skeletal muscle of the body. The designing band of the antenna is ISM (Industrial, Scientific and Medical) Band. The substrate is designed using FR4 substrate which works at the frequency range of 2.38GHz to 2.49GHz. The working frequency of the antenna is 2.45GHz. The body phantom model has been designed using the skin, fat and muscle. The designed antenna is simulated in the CST Microwave Studio. This Antenna helps for monitoring the health of the people. To reach the desired result smaller circular holes have been cut from the patch. It increases the electrical path of the Antenna. When the tumor is inserted in the body, the results showed that all the measuring parameters have been changed by some value but the Return Loss decreases due to the lossy behavior of the skin. It shows that the designed antenna is compatible for detecting the tumor. The tumor affected body part SAR value is .00185W/kg when the antenna is planted 10mm far away from the body phantom. The result shows that it fulfills the minimum SAR requirements and is compatible with Biomedical Applications.
