Abstract

In this paper, a planar microstrip patch antenna operating in FCC MBAN for tumor detection is presented. The proposed antenna is constructed using a triangle-shaped patch with inset feeding. It is fabricated on an Arlon AD1000 substrate. Some of the parameters are assumed, and optimization is carried out to achieve greater performance. This prototype is placed on a human tissue mimicking model and simulated considering the cases of body model with tumor and without tumor. The designed antenna resonates at 2.37 GHz with 10 dB bandwidth of 3 MHz meeting the requirements specified by the FCC. Further, the introduction of a slot in the ground plane gives a half power beam width of 20.6° with directivity of 8 dB. This narrow beam is suitable for scanning application in microwave imaging. The fabrication of the antenna is carried out, and measurements are done to assess the performance of the antenna. Body phantom is created using petroleum jelly and mixture of wheat flour and water. The fabricated antenna is placed on the created model, and the variation in the resonant characteristics has been observed with the presence and absence of tumor.
