Communication environment analysis of textile antenna using ray tracing method

Abstract

Biological information monitoring systems are widely used to obtain and monitor the vital signs of patients in hospitals. However, the current system mainly uses the 420-450MHz band, making it difficult to manage channel switching, adding and removing equipment and so on, unless you are an expert in wireless communications. There is also the problem of having to carry a transmitter that is the same size as a small terminal. Therefore, we proposed a textile antenna using the 5.2GHz band as a replacement for the system’s transmitter antenna. In this paper, we report the antenna characteristics of the transmitter antenna designed by the authors when it is attached to the human body, the received power results of the transmitter power by analyzing the textile antenna in a simulated real-world environment model.
