An all-textile H-plane substrate integrated waveguide (SIW) horn antenna for millimeter-wave wireless body area network applications is proposed. A coaxially fed SIW H-plane horn is designed for radiation toward a human body surface. To reduce the radiation to a human body and simultaneously increase the radiation to the human body surface, an extended corrugated ground is attached in front of the aperture of a horn. All components are made of textile materials. The simulated 10 ㏈ return loss bandwidth is 2,400 ㎒ (26.7–29.1 ㎓), which covers a potential candidate frequency band for 5G communication. The simulated and measured results show that the proposed antenna has a directional radiation pattern toward the body surface and a low power density below the antenna.
