The result is obtained by examining and comparing the above two parameters. 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. 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 proposed system makes use of the patch antenna in the healthcare domain. It also extends its application to RFID (radio frequency identification) fields and healthcare. This paper focuses on the improvement in the return loss and antenna operating bandwidth of the flexible antenna to make it suitable for WBAN application.Ī 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. The antenna design, simulation, and performance analysis have been conducted using Computer Simulation Technology (CST) software. The accumulated surface current is 174 A/m on the radiating patch with a maximum realized gain of 3.42 dB and the maximum radiation efficiency of more than 60%. In addition, the VSWR value is 1.03 at the resonant frequency with an increase of 7.5% in the realized gain compares to the antenna without DGS. The designed antenna is expected to operate at 2.45 GHz within the ISM band range and the return loss is-37.33dB with wide-10dB bandwidth of 101MHz. DGS is used to further enhance the antenna performances. This paper presents an inset-fed microstrip patch antenna designed on a rubber substrate with a defected ground structure (DGS). The physical flexibility has a significant impact on microstrip antenna design for wireless body area network (WBAN) application and designing such an antenna on a flexible substrate has many challenges.
