Abstract

This paper presents a compact printed dual-band WLAN antenna with a shorted coupling strip for mobile terminals. A shorted coupling strip is utilized to improve impedance matching at the upper band and a chip capacitor is used to reduce an antenna size. The proposed antenna area is 10 × 5 mm² with a ground size of 70 mm × 40 mm. The proposed antenna yields a VSWR of better than 3:1 at dual bands of 2.39~2.49 GHz and 5.07~5.88 GHz. The measured gain is 1.3 dBi at 2.44 GHz and 3.7 dBi at 5.35 GHz, respectively.
