摘要

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.
