Abstract : Direction finders of the stacked-beam type exhibit optimum performance if the beam shape remains essentially Gaussian in all elevation planes which lie in the ajor lobe of the principal azimuth-plane pattern. The method of synthesis, an extension of Woodward's method, includes the effects of the phase distribution in the aperture. For a prescribed Gaussian shape of the major lobe of the radiation pattern in the principal elevation plane, several antenna apertures have been synthesized. The radiation patterns in certain off-axis elevation planes were calculated for each of the synthesized apertures. One aperture, in particular, exhibits the desirable property that the prescribed shape of the major lobe of the radiation pattern is preserved quite well in all the elevation planes at azimuth angles extending out to the -6 db point of the principal azimuth-plane pattern.
