Fullwave analysis of the radiative properties of short-circuit discontinuities in modified coplanar stripline

Spectral-domain analysis is used to determine the radiation loss of short-circuit discontinuities in modified coplanar stripline. These results are compared with those for short-circuit discontinuities in a coplanar waveguide and it is shown that, in the two cases analyzed, the radiation loss of the modified coplanar stripline short circuit is lower than that of the coplanar waveguide short circuit. The physical basis for this behavior is discussed.<<ETX>>
