| Abstract: | This paper presents the design of aKband frequency scanned array in an RG 96/U waveguide. The radiating elements consist of slots machined in the narrow wall of the guide. experiment-resluts of the measured slot conductances for the antenna elements and the feed system are given for slot spacings of 0.25 inches and various slot orientations and depths. Theoretical optimum efficiencies for uniform, Chebyshev, and Taylor distributions are also presented. Finally, the experimental results for a 400-element planar array are given. |
