In the above paper, the approximate formula for the characteristic impedance Z of a microstrip line, with substrate dielectric constant /spl epsi/, and thickness to width ratio h/W, should be Z/spl cong/ 377/ /spl radic//spl epsi//sub r/ {1-2 / /spl pi//spl epsi//sub r/ (h /w) [(1+/spl epsi//sub r/) ln (2h / W) - 2.230 - 4.554/spl epsi//sub r/ - (4.464 + 3.89/spl epsi//sub r/) h / W]} /sup - 1 / 2 /, for h/W small.
