| contents | Design and simulation of Quasi Crystal based Artificial Magnetic Conductor (AMC) Circular Microstrip Patch Antenna for tumor detection is discussed. Initially, a Circular Microstrip patch antenna is designed with a resonant frequency of $2.45 \, \text{GHz}$. The performance of the designed antenna can be improved by incorporating AMC in order to avoid surface waves. In this paper, we propose a novel technique for detecting malignant tissues in a more focusing manner using a Penrose patterned Quasi crystal. Quasi crystals act as a focusing device as it can transmit electromagnetic waves in a narrow direction. The tumor of size $3 \, \text{mm}$ is placed at a particular location specifically at $(0,0,10)$ in the breast phantom model. Our aim is the proposed model could identify the exact tumor location or the nearest co-ordinates of the actual location. Scattering parameters $S_{11}$ and $S_{22}$ obtained at $-10.30 \, \text{dB}$ and $-9.15 \, \text{dB}$ respectively at the tumor location $(0,-4,30)$ without the presence of Quasi crystal. Results were compared in each stage with and without Penrose Quasi crystal based patch antenna. The Quasi crystal based model was simulated and the results $S_{11}$ and $S_{22}$ parameters got improved at $-10.02 \, \text{dB}$ and $-9.37 \, \text{dB}$ respectively at the tumor location $(-1, -1, 13)$. The total specific absorption rate (SAR) of the proposed model is $0.139 \, \text{W/kg}$. Hence the proposed model is highly bio-compatible and safely applicable for human body. |
