Textile Antenna With Telkom University Logo Patch For WBAN Communication At 2.4 GHz Frequency

Wireless Body Area Network (WBAN) is a wireless communication network designed to monitor the condition of the human body. This monitoring is very important to ensure that the body stay healthy when carrying out daily activities. Antenna is one of the important devices in WBAN communication. This paper focuses on design and realization a textile antenna with patch in the form of Telkom University logo which operates at 2.4 GHz frequency of the ISM (Industrial, Scientific, and Medical) band. This antenna uses trunk cut method on the feed line to widen bandwidth. The result has dimensions (101.49 $\times 110.10 \times $ 7.6) mm with 1.265 GHz bandwidth when free space and 1.306 GHz bandwidth when on-body. The measurement results obtained 1.16 VSWR when free space and 1.35 VSWR when on-body at 2.428 GHz frequency. The simulation results obtained 7.26 dBi gain when free space and 7.34 dBi when on-body, unidirectional radiation pattern, and SAR 0.715 W/kg.
