Abstract

A novel low-profile uniplanar dual band coplanar waveguide (CPW)-fed monopole antenna/electromagnetic band-gap (EBG) combination, exhibiting bandwidth enhancement, is presented. Prototypes of the monopole antenna alone and combined with the EBG in the same layer are manufactured using laser micromachining. The characterization results of the manufactured prototypes in terms of return loss and radiation pattern measurements in an anechoic chamber are shown for comparison.
