The Flexible Antennas Using Silver Paste with Micro Particles

Abstract

In this paper, the effect of conductive silver paste with micro particles (5 μm) is investigated on the flexible microstrip patch antenna design. Preliminary studies on this antenna design are made at 4.65 GHz resonance frequency by utilizing kapton polyimide substrate and silver material in CST simulation environment. In addition to the design work, the antennas are fabricated at different sintering temperatures and parameters such as return loss and bandwidth are measured. The effects are analyzed in light of the SEM images of the fabricated antennas. The measurement results of fabricated antennas demonstrate that, as the temperature increases the resonance frequency is also increased. © 2019 IEEE.
