Abstract

In this paper, a Frequency Selective Surface (FSS) radome with a horn system was analyzed. A new coupled resonator spatial filter (CRSF) consisting of hexagon patch and circular aperture was firstly used in W-band. The FSS element shows stable performance with the polarization state and angle of incident wave. The horn composed of the FSS radome placed in its near-field region was designed. The antenna patterns shows that the FSS radome keeps good insertion loss, radiation patterns of horn within the designed pass-band, and reflects signal within the stop-band. The design of FSS radome shows performance advantage in reducing RCS at stop-band for its planar shape. The results provide the basis for our later studies of conformal shape radome.
