Design of a compact modified inverted-L antenna with a ground stub is proposed for Wi-Fi applications. With the ground stub structure, the impedance bandwidth for 2.45-GHz band enhances from 13.1% to 15.7%, and the impedance bandwidth for 5.2/5.8-GHz bands improves from 10.1% to 19.9%. The performances of the antenna with optimized parameters are characterized in terms of reflection coefficient, gain, and radiation pattern measurements in an anechoic chamber. The measured result satisfies Wi-Fi frequency specifications.
