Phase-Variation Microwave Displacement Sensor With Good Linearity and Application to Breath Rate Monitoring

This article presents a novel highly linear reflective-mode displacement sensor based on planar microwave technology. The sensor consists of two parts: 1) the stator, or reader, a one-port transmission line terminated with a matched load and 2) the movable part, or tag, a dielectric slab with an ele...
