Abstract
A noble planar monopole antenna with a staircase shape and very small volume (25 × 26 × 1 mm3) is proposed in this paper. With the use of a half-bowtie radiation element, the staircase-shape, and a modified ground plane structure, the proposed antenna has a very wide impedance bandwidth measured at about 11.6 GHz (2.9 GHz ∼ 14.5 GHz, bandwidth ratio about 1:5) below VSWR 2 including the WLAN band notched in the vicinity of 5 GHz. An omni-directional radiation pattern is obtained. The electrical and physical characteristics of the proposed antenna make it attractive for use in ultrawide band systems.
