Several additions to the metallic Electromagnetic Code Consortium EMCC benchmarks are described. The new geometries include a cube, a prism, a pyramid and a trihedron. These geometries include edge, corner, and multipath scattering effects. In addition, the first EMCC antenna benchmark composed of an array of elements on a finite metal plate is described. Measured and computed scattering or radiation data for each new geometry is shown. Computed data is generated with the FISC, AIM, and XPATCH codes. Where applicable, sources of discrepancy between the measured and computed results are discussed. For some of the objects, the measured data is taken in two passes to improve the dynamic range. However, at present only one pass of the data is available, resulting in some error near the top or the bottom of the data range.
