This paper studies the feasibility of two-dimensional microwave respiration monitoring. According to a real human computed tomography image, the chest cavity is established in the simulation, which is more realistic and persuasive. Based on the formula of 4-Cole-Cole expressions, some corresponding parts of the human body’s relative permittivity and conductivity are calculated. Moreover, the dielectric properties within the lungs will change during respiration, and the changes will affect the transmission of microwaves in the human thorax. In this paper, the frequency of 433MHz and 915MHz is adopted to monitoring respiration. The simulation data is collected and analyzed to get intuitive maps. In summary, this study illustrates the feasibility of microwave respiration monitoring.
