Abstract :
A novel compact coplanar stripline (CPS)-fed antenna for ultra-wideband (UWB) application is investigated. The proposed antenna consists of a staircase-shaped radiator together with a shorted strip. The prototype is designed on a substrate of dielectric constant 4.4, with an overall size of 25 × 7 × 1.6 mm3. The antenna offers a 2:1 voltage standing wave ratio (VSWR) bandwidth from 3.1 to 11.4 GHz, with an average gain of 3 dBi and average radiation efficiency of 75% throughout the band. The measured group delay and transmission characteristics show that the proposed antenna is a good candidate for UWB communication systems.
