Abstract:
A novel co-planar waveguide (CPW) ultra-wideband (UWB) aperture antenna is presented. The antenna consists of a rectangular aperture on a printed circuit board ground plane and a mushroom-shaped exciting stub. The mushroom-shaped stub is simple and has less parameter, which is convenient to analyze and optimize. The antenna has a compact aperture size 22 × 13mm2, fabricated on FR4 substrate with dielectric constant of 4.3, thickness of 1.5 mm. The antenna is successfully implemented and measured, which has 8.3 GHz match bandwidth (VSWR < 2), and stable radiation patterns.
