In this paper, a folded dipole antenna operating in the ISM band is presented. The antenna was designed by adjusting the ratio of the folded dipole arms and incorporating a matching stub technique. Each element of the antenna was optimized through a parameter sweep. The analysis confirmed that the slot length in the folded dipole and the width of the matching stub enable fine-tuning of the operating frequency. Furthermore, the antenna characteristics can be effectively optimized by adjusting the position of the matching stub and the arm ratio of the folded dipole. The antenna has a compact size of 60 mm × 38 mm × 3 mm and is fabricated on an FR4 substrate. It achieves a 10 dB bandwidth from 2.37 to 2.51 GHz, corresponding to a bandwidth of 140 MHz. The radiation pattern resembles that of a half-wavelength dipole, and the maximum gain is 1.59 dBi. Based on the results of this study, the proposed antenna is considered suitable for applications in IoT, ZigBee, and smart factory environments.
