Development of a linear antenna array on a flexible substrate

The paper describes the procedure for developing a flexible antenna configured for Wi-Fi 2.4 GHz. The substrate material is a polyamide film with the thickness of 125 μm, the dielectric constant of 3.4, and tanδ = 0.004. The characteristics obtained during the simulation and experiment are presented. In addition, an assessment was made of the effect of the bending of the antenna sheet on its characteristics. Antennas on a flexible substrate are much easier to transport (roll up), and they can also take the form of a surface relief on which they are mounted.
