Design of simple printed Dipole antenna on flexible substrate for UHF band

In this article, we introduce an antenna printed on a flexible substrate. This prototype is intended for a flexible display device. The flexible screen has the advantage of being finer and more shock-resistant than the current slabs while allowing smart-phones to adapt to different uses due to its flexibility. The suggested antenna is a dipole with two symmetric frameworks printed on a Kapton polyimide substrate with a relative permittivity of 3.45 and a loss tangent of 0.002. The parametric study performed is based on the length and width of the proposed antenna; it shows that the proposed architecture is adapted to operate in the UHF band. The simulation and measurement results are in good similarity.
