A miniaturized dual-band v-shaped monopole antenna fed by v-stub is presented. The proposed antenna performs two resonant modes covering dual-band of wireless standards, for operating in the IEEE 802.11 a,g,n WLAN (5.15-5.35 GHz and 5.725-5.825 GHz) and IEEE 802.16e WiMAX (3.3-3.69 GHz and 5.25-5.85 GHz) bands. The antenna is printed on a 1.6-mm thick FR-4 substrate and the relative permittivity of 4.4, is fed by cross v-strip line a 50Ω with SMA connector. The antenna size is 18 mm × 26 mm × 1.6 mm in dimensions. The measured results show that the miniaturized size antenna achieves a broad operating bandwidth of 3.24–3.71 GHz and 4.85-5.87 GHz for |S11| < -10 dB and omnidirectional beam. The measured gains of the antenna at 3.5 GHz and 5.5 GHz frequencies are 1.51 dBi and 2.34 dBi, respectively.
