Abstract

This paper presents a dual-band antenna for a wireless local area network (WLAN) system with the frequency of 2.4–2.5 GHz and 5–6 GHz. The proposed antenna is a patch antenna consisting of two circular radiation plates. They are stacked above and below the multilayer substrate, connected by wire, and fed by the coaxial probe. From simulated and measured results, the proposed antenna has an input impedance close to 50 W and |S11| below -10 dB in a frequency of 2.4–2.5 GHz and 5.0-5.3 GHz, the gain is 1.9 dBi at 2.45 GHz and 2.36 dBi at 5.2 GHz, respectively. The antenna can be effectively used in both frequency bands of wireless local area networks.
