Abstract :
An optimized coplanar waveguide (CPW)-fed, ultra-wideband (UWB) printed radiator is presented. Balanced shapes are incorporated to the radiating section so that the impedance is matched in a balanced manner over the intended bandwidth. Both the CPW-feed and the antenna sections are realized on one single layer of standard RT5870 high frequency laminate. The radiator possesses good UWB-characteristics in the designed spectrum (4.2 to 14.2 GHz). These include nearly perfectly symmetrical patterns, no side-lobes, no cross-polar components in the symmetrical axial plane and low cross-polar components in all other planes, balanced impedance bandwidth, and almost 4 octaves impedance bandwidth.
