تحسين منظومة الكترونيات مستقبلات شبكات منطقة الجسم اللاسلكية (WBANs)

Abstract

Wireless body area networks WBAN(Wireless Body Area Network) has gained attention due to the significant development in the field of electronic wearable devices through the use of fitness trackers, smart watches, healthcare devices, GPS(Global Positioning System) devices and others. WBAN encompasses three distinct communication modes: in-body, on-body, and off-body modes based on the location of the signal nodes. In this article we will address antennas where these devices used in WBAN network should be low cost, low energy consumption, and high bit rate. A rang of frequency bands has been allocated for this purpose, including 400MHZ for implantable medical communication networks, 2.4GHZ and 5.8GHZ for industrial, scientific, and Medical (ISM) application, and (3 to 10)GHZ for Ultra-Wideband (UWB) services. In this article, a wearable antenna operating in the ISM band will be designed, suitable for the human body in terms of small size and light weight, in addition to a wide frequency band. This will be achieved by controlling the type and height of the antenna substrate, and then creating slots in the patch antenna to provide additional resonant frequencies and improve bandwidth.
