Compact Terahertz Antennas for Body-Worn Wireless Communication Systems

Wireless body area networks (WBAN) are used extensively because of the increasing use of wireless networks and various IoT devices. A Wearable Patch antenna is used to develop various WBAN applications. In wireless communication, due to the paucity of available spectrum, the need for high data rate should be considered in the future convincing systems. Benefiting from a much wider bandwidth, terahertz (THz) connectivity becomes the promising technology for future 6G networks. Therefore Terahertz (THz) frequency band is considered in this paper and the gold patch material is used for antenna design in WBAN system. The proposed model is based on the evaluation of the link budget and the path attenuation. A compact size rectangular patch antenna with inset feed is analyzed and designed for signal transmission in wireless body area networks. The operating frequency of the antenna is considered to be 0.75 THz. The proposed antenna is designed and simulated by using High-Frequency Structure Simulator (HFSS) and the proposed antenna attains better gain, VSWR and return loss. In WBAN, the amount of transmitted power at various distances between the transmitter and receiver is analyzed by using various modulation techniques.
