Antenna Design for IoT and Biomedical Applications

Abstract

Given the current state of affairs, the development of wireless communication has had to go through numerous evolutionary stages. The concept of wireless communication, however, has been around for over a century. Personal communication both ON and OFF the body requires body area networking (BAN). The modules of BAN systems include wearable and textile antennas used in patient monitoring, healthcare devices, firefighting uniforms, and other applications. These have antennas that are worn or carried closer to the body. The third and final issue is the need for a reliable power supply, especially in extreme or remote locations, for medical and communication devices. This investigation seeks to understand the human body’s influence on the various parameters of the biomedical antennas. The 10dB bandwidth in the human body is significantly larger than the corresponding bandwidth in a lossless medium. In a lossy medium, the frequency of a resonance is lower than in a lossless one. Increasing bandwidth is one way to combat the frequency detuning impact produced by human body losses. © 2024 selection and editorial matter, Puran Gour, Nagendra Singh, Rajesh Kumar Nema, Ravi Shankar Mishra and Ashish Kumar Srivastava; individual chapters, the contributors.
