Abstract:	A dual-band antenna design using a dual-feed monopole slot is proposed for wireless local area network (WLAN) applications. Unlike designs using multiple slots for multi-band radiation, the proposed single-slot configuration is less complex, and the multi-band response is excited by a specially designed antenna feed. At 2.4 GHz, the antenna is operated in the resonant mode of the quarter-wavelength slot. With the proper phase difference between the voltages at the feeding microstrips, a travelling-wave mode is excited at 5.5 GHz. The tuning mechanisms of the antenna centre frequencies and bandwidths are explained in detail, and the position and shape of the slot are adjusted for better radiation responses. Simulation and measurement regarding the reflection coefficients and radiation patterns of the antenna are conducted.
