Abstract


The Octagonal UWB antenna with an octagon aperture is designed and demonstrated experimentally for RCS reduction applications. In this design, the required RCS reduction is achieved by adopting the size reduction technique. The size miniaturization is obtained by converting circular patch into the octagonal. Afterward, non-effective area of the patch is subtracted in the form of octagon aperture. The scattering performance of the modified antenna is satisfactory in the entire operational frequency range. In addition, the modified antenna has advantages on reference antennas inthe RCS reduction. The outcomessuggest that the proposed design will provide a future prospect for low RCS antenna applications.
