An ellipsoidal frequency selective surface
Abstract
The frequency selective surface (FSS) considered reflects radio waves within a small frequency band, but it is nearly transparent to radio waves outside this band. The ellipsoidal FSS represents an ordered arrangement of dipole-like elements on an elliptical surface. Attention is given to the theory of FSS operation, the approach used in the design process, the techniques considered for fabricating the flat surface FSS, the test chamber, the transfer of the design for the flat FSS to the ellipsoidal curved surface, and the test results. The frequency-selective response of the FSS shows that the FSS is highly reflective near 9 GHz and is relatively transparent above 1.05 GHz and below 7.5 GHz.
