Artificial Magnetic Conductor-Based Microwave Button On Textile Substrate

Abstract

This paper is proposing textile substrate-integrated button composed of textile integrated waveguide. Such pressure sensor could be used as an interface button or as a sensor of person presence. Proposed structure consists of two layers of substrate. Lower one is a straight section of the waveguide with slots feeding upper one is a closed section of waveguide forming a resonator stopband filter. Later, the simple textile integrated waveguide is changed to waveguides utilizing periodic cells as the artificial magnetic conductor (AMC) which could be printed instead of sewing vias by metallic wires.
