Abstract

This paper proposes a new approach to suppress the harmonic radiation from a microstrip patch antenna by embedding several grounded-pads in an antenna substrate. The grounded-pad is composed of a rectangular metal pad and a thin metal wire connecting between the pad and the ground plane. Even though the pad is very small in size, it works as a deep and narrow band elimination filter. The basic behavior of this pad is studied theoretically by the FDTD method. Finally, several grounded-pads are embedded in the substrate of a microstrip patch antenna to suppress harmonic resonances.
