This paper introduces a novel compact wideband CPW-fed slot antenna comprising of an E-shaped patch that is excited with a trident shaped feed-line structure. The antenna design exhibits a very wide operating bandwidth of over 168% with S11 < -10dB in the frequency range 1.6 to 18.9GHz. The antenna's radiation characteristics are stable across this wide bandwidth. The proposed antenna exhibits high polarization purity with cross-polarization level that is well below -40dB. A comprehensive parametric study was carried out to get insight on the effects of various antenna parameters that enable optimization of the antenna's performance. This antenna easily fulfills the requirements for ultra-wideband (UWB) wireless communication systems as specified by FCC over the designated band 3.1GHz-10.6GHz.
