Conductive inkjet printed ultra-wideband (UWB) planar monopole antenna on low cost flexible PET substrate material

Abstract

Printed antennas on flexible substrate material are highly desirable for flexible circuits and wearable applications. An ultra-wideband (UWB) printed planar monopole antenna operating at 3.4-12 GHz was designed, modeled, fabricated, and tested for scattering parameters and radiation pattern response. The measured reflection coefficient magnitude for the fabricated antenna exhibits a bandwidth of 8.6 GHz, with near omnidirectional radiation patterns. For the sake of brevity, only some selected results are presented here.
