E-Plane Integrated Circuit Filters with Improved Stopband Attenuation (Comments)

In the above paper, in rows 1 and 2 of Table 1 on p. 1392, the optimized design data should read as given below. These data relate to the filter performances shown in Figs. 3 and 4 (midband frequency f₀ = 38.66 GHz). The data originally reportedl pertain to filters not presented in the figures, with a midband frequency of f₀ = 39.5 GHz.
