Abstract
In recent days, it has been mandatory to embed sensors in almost all electronic products to make the products as smart gadgets. RF systems play a key role in enhancing the sensing capability of those gadgets in easier and affordable way. RF sensors defined to be resonated at the designated frequency is considered accurate within the bandlimit. RF sensors manufactured are high in demand in sensing wi-fi signals, when moving in anonymous regions. The demand gives an idea of developing a flexible wi-fi sensor with microstrip-coplanar waveguide-microstrip configuration on a paper substrate, for affordable applications. The sensor utilizes band pass characteristics at 2.45 GHz band over a bandwidth of 320 MHz. The design of the proposed sensor utilizes 60.5 × 30 × 0.358 mm3 volume. The proposed chip-less passive prototype will be advantageous in many commercial applications and cheaper one if manufactured in bulk.
期刊介绍：
Analog Integrated Circuits and Signal Processing is an archival peer reviewed journal dedicated to the design and application of analog, radio frequency (RF), and mixed signal integrated circuits (ICs) as well as signal processing circuits and systems. It features both new research results and tutorial views and reflects the large volume of cutting-edge research activity in the worldwide field today.
A partial list of topics includes analog and mixed signal interface circuits and systems; analog and RFIC design; data converters; active-RC, switched-capacitor, and continuous-time integrated filters; mixed analog/digital VLSI systems; wireless radio transceivers; clock and data recovery circuits; and high speed optoelectronic circuits and systems.
