A flexible C-band antenna design using conductive wire weaving technique is introduced. An antenna consists of three layers: a groundplane, a radiator, and a parasitic element on top. The square radiator element is made of woven ladder yarn. At the same time, both the grounding element and the parasitic element are made of flexible copper sheets. On the other hand, the antenna substrate is made of denim material with a dielectric constant of 1.7 and a loss tangent of 0.024. The antenna design is optimized using finite element method (FEM). The antenna is designed for use in the C-band with a center frequency of 5.3 GHz. Simulation results show that the antenna design has a gain of 4.8 dB, a reflection coefficient bandwidth (S11) of 7.02%, and the highest efficiency of 62.7% at the center of the operating frequency. Based on the simulation results, the weaving technique produces good antenna performance and can be used in various C-band applications. © 2023 IEEE.
