Abstract :
In this paper a new approach of ultra sensitive sensor based on coplanar waveguide is proposed. This sensor consists of two Wilkinson power dividers, makes use of the path difference of the two branches resulting in the opposite in phase, thus the weak signal changes emerge from the dramatically reduced background and the sensitivity is greatly improved.
