Abstract :
In this letter, we present an innovative solution to achieve high efficiency printed antennas made on paper substrate. A corrugated cardboard is introduced for the first time for RF circuits. This substrate has been characterized with small perturbation method. It presents a dielectric constant of 1.41 and loss tangent of 0.042. Subsequently, patch antennas were realized on corrugated cardboard and classical paper substrate. A measured gain of 5.12 dBi is reached with corrugated cardboard compared to -3.24 dBi for classical paper. Simulation results show a good agreement with measurement.
