Abstract
A microstrip directional coupler with a microfluidic superstrate in the coupling gap is investigated.In the microfluidic channel, relative dielectric constant values ranging from εr = 81 to εr = 1, deionized water and air are studied, respectively. The tuning range of the coupler is evaluated experimentally and compared to its full-wave simulation.
