The feasibility of operating a compact antenna test range at 35 GHz has been demonstrated. A compact range of simple construction has been shown to have a performance only slightly inferior to the performance at X-band. Diffracted rays from the edges of the source reflector can degrate the purity of the electric field. This has been investigated and sucessfully controlled by serrating the rim of the...
A uniform diffraction solution is given for an electromagnetic wave incident on perfectly conducting surface having a discontinuity in curvature. The solution is derived from an asymptotic evaluation of the physical-optics integral, and correction factors are deduced to retrieve the rigorous nonuniform result away from the reflection boundary.
