In this study, a folded dipole antenna is proposed using the Finite Difference Time Domain (FDTD) method, which can work on the SHF spectrum. So, it can be applied to wireless communication tools. The folded dipole antenna is designed using copper material with a thickness of 0.029 mm. After that, it was coated with FR-4 with a size of 50 × 30 × 1.6 mm3. For the communication device to work in low signal areas, the folded dipole antenna must be reconfigurable. The reconfigurable type used is optically reconfigurable. So, on the right and left sides of the antenna, a red photodiode is installed. Based on the simulation results, it works at a frequency of 9.021 GHz before being irradiated by a red laser at 650 nm 5 mW and 6.660 GHz after being irradiated by a red laser. Furthermore, the change in frequency of the folded dipole antenna becomes wider, so a resonator is added. Based on the simulation results using a resonator, it works at a frequency of 10.781 GHz before being irradiated by a red laser and 2.559 GHz after being irradiated by a red laser.
