Abstract
In this paper, a CPW-fed sectoral antenna is presented with a modified ground plane. The proposed antenna is compact with a size 15 × 12 × 0.8 mm3. Later, using T and curved Y-shaped strips WLAN (4.82 GHz ~ 5.22 GHz) and WiMAX (3.38 GHz ~ 4.08 GHz) bands are rejected. In both notch bands VSWR >>2 is observed. Parametric analysis is done to know the effect of strips used for band notch operation. An empirical formula relating to notch frequency and strip length is suggested. Ansys HFSS V.20 is used to design the proposed antenna.
