Abstract:

To reduce the RCS (Radar Cross Section) of a microstrip patch antenna, the UC-EBG structure is used as the ground plane of a microstrip patch antenna because of the stop-band property of the UC-EBG. In the pass-band, the UC-EBG can let many more incident waves pass. Therefore, it can effectively reduce the RCS of the microstrip patch antenna outside operating band. The simulated and measured results are in good agreement with each other and show that this method is effective.

Key words: microstrip patch antenna, ground, radar cross section, electromagnetic band-gap
