A wearable textile antenna based on the fundamental mode of an eighth-mode substrate-integrated waveguide is presented, operating in the UHF frequency band, at 915 MHz. The proposed structure has a compact size, and presents a very good isolation from the human body. Compared to its SIW resonator counterpart, the proposed antenna size has been reduced by almost 87.5%, without degrading its performance. It has been simulated using CST Microwave Studio, with a broadside radiation pattern. All these features make this antenna very promising for Lo-Ra systems and applications, such as internet of things (IoT) applications. © 2021 URSI.

Abstract
A wearable textile antenna based on the fundamental mode of an eighth-mode substrate-integrated waveguide is presented, operating in the UHF frequency band, at 915 MHz. The proposed structure has a compact size, and presents a very good isolation from the human body. Compared to its SIW resonator counterpart, the proposed antenna size has been reduced by almost 87.5%, without degrading its performance. It has been simulated using CST Microwave Studio, with a broadside radiation pattern. All these features make this antenna very promising for Lo-Ra systems and applications, such as internet of things (IoT) applications. © 2021 URSI.
