Figure 44

(a) Schematic of the beamwidth controlling using metasurface. (b) Photographs of the fabricated FSS for beamwidth controlling. (c) Response of reflection and transmission coefficients to different capacitance values at the interesting frequency region. (d) Photograph of the low RCS antenna loading partially absorbing metasurface. (e) The RCS results for the PRS antenna with and without PRS. (f) Measured -plane far-field patterns for the beamwidth manipulation antenna at 5.5 GHz. Figures are reproduced from [224].
