Ultra-Wideband (UWB) Antenna Radiation on Action Potentials in Human Nerve Fibers
Keywords:Action Potentials, Nerve Fibers, UltraWideband (UWB), Antenna, Human Model,
AbstractThe increasing and rapid development of wireless communication technology such as mobile phone, radio base station, power transmission line, medical devices and microwave antenna are being concerned to all parties due to its electromagnetic fields exposure to human. Some of these devices have been classified as extremely low frequency (ELF) non- ionizing radiating devices. These electromagnetic fields will transform into microwave radiation or electromagnetic radiation that can lead to biological hazardous effects, thus affects human health. A human nervous system which the main part of the human body also can’t escape from being exposed to electromagnetic radiation. Therefore, this study is to investigate the effect of microwave radiation from UltraWideband antenna frequency towards human arm action potentials (AP) in nerve fibers. In this paper, a CPW-fed modified circular patch antenna for UWB application is proposed. This antenna is designed by using biocompatible Poly (methyl methacrylate) (PMMA) substrate with dielectric constant, Ɛr = 2.8 and substrate’s thickness, h = 1.6mm. The simulation is done by using Computer Technology (CST) software. The antenna operates at frequency range 2.930-19.032GHz. The antenna also has the nearly omnidirectional result that is suitable for UWB application. The homogeneous human arm model with the presence of other human tissues such as fat, muscle, skin, bone and nerve are designed which is expected to improve the understanding of radio propagation inside the human body. The UWB antenna will be implanted in skin. CST Microwave Studio is one of the EM modeling code which can be used for bio electromagnetic purpose.
