- W1589644564 abstract "Abstract : Three Archimedean spirals were tested for antenna patterns and coupling patterns: (1) circular, (2) square, and (3) dielectric-cavity-backed circular. The latter was used in the fundamental mode, with out-of-phase currents at the feed. The square spiral exhibits a broader beam, a better ellipticity ratio, and a larger VSWR over the band, than of the circular spiral. The effect of the dielectric is to broaden the beam, since the antenna radiates from a smaller region. This broadening effect is significant when the cavity thickness is greater than one-quarter wavelength. Another square spiral, oppositely wound, was tested for coupling patterns, and exhibited essentially mirror-image behavior to the first square spiral. A theoretical consideration of mounted flush-horn antennas indicates rough coupling estimates may be obtained rather simply from curves given. The feed and geometry of the horn determine the aperture field distribution; this, in turn, determines the fields in space and along the ground plane. Phase variations due to horn flare tend to smooth out sidelobes and broaden the beam. Fresnel zone phenomena are not considered. (Author)" @default.
