## Abstract The Bragg wavelength regime of an axially excited, chiral sculptured thin film is shown to contain resonances of electric, magnetic, and mixed types. The resonance wavelengths initially change rapidly, but later stabilize, with respect to the film thickness. The center wavelength of the
ground plane, becomes a planar rectangular monopole antenna when the bottom ground plane is removed. A parametric study of the rectangular monopole antenna has been carried out to optimize the bandwidth. We obtained a mea-Ž . sured broad bandwidth from 1.220 to 3.550 GHz 1:2.9 . The radiation patter
