A microstrip antenna, commonly known as patch antenna is widely used in mobile communication as it can be easily
fabricated and is also well known for its advantages such as low profile and low cost. It also extends its application to RFID
(radio frequency identification) fields and healthcare. The proposed system makes use of the patch antenna in the healthcare
domain. A slotted microstrip patch antenna is designed by using CST software with a return loss of -37db and VSWR (Voltage
Standing wave ratio) value 1.7 to detect tumour inside the brain. The designed antenna is placed in the head phantom with and
without tumor model and the difference in parameters such as S-parameter and SAR (Specific Absorption Rate) is analysed. The
result is obtained by examining and comparing the above two parameters. By this analysis, we can state whether the person has
a brain tumor or not. The antenna works under the frequency band of 2.5– 2.9 GHz. This system can be used to monitor the
patient at a remote distance.
