In this paper, a review of the state-of-the-art chipless radiofrequency identification (RFID)
technology is carried out. This recent technology may provide low cost tags as long as these …

Radio-frequency identification (RFID) sensors are one of the fundamental components of the
internet of things that aims at connecting every physical object to the cloud for the exchange …

This paper presents a microwave sensor using a pair of split-ring resonators (SRRs). The
sensor is designed by loading a microstrip transmission line by two identical SRRs on its …

Comprehensive resource detailing the latest advances in microwave and wireless sensors
implemented in planar technology Planar Microwave Sensors is an authoritative resource …

With the advent of emerging technologies, traditional agriculture practices are now shifting

A differential microwave permittivity sensor and comparator is designed using a microstrip
transmission line loaded with a magnetic-LC resonator. The microstrip transmission line is …

This letter presents a novel microwave-based rotation sensor having a wide dynamic range
to detect and measure the angular displacement in terms of the change in resonant …

This article proposes a novel reflective-mode phase-variation sensor based on a movable
step impedance resonator (SIR) implemented in coplanar waveguide (CPW) technology …

This article presents a novel sensor for detecting and measuring angular rotation and
proximity, intended for rapid prototyping machines. The sensor is based on a …

In this paper, a displacement sensor based on an open-ended step-impedance transmission
line is reported. The sensor operates in reflection, and the output variable is the phase of the …
