A compact all-textile on-body SIW antenna for IoT applications

A compact all-textile on-body substrate integrated waveguide (SIW) antenna for internet of things (IoT) applications is proposed. By using the half-mode substrate integrated waveguide (HMSIW) technique, the antenna has a compact size while fully covering 5-GHz Wifi band and has a gain of 6.08 dBi at the center frequency. In order to integrate with an on-body IoT device, all components of the proposed antenna are made of textile materials and the human body effect is analyzed using the two-thirds human equivalent phantom.
