Comments on "Surface wave enhanced broadband planar antenna for wireless applications"

For original paper see K.M.K.H. Leong et al., ibid., vol. 11, pp.62-4 (2001). The above paper claims to present "a new class of broadband antenna in which TE/sub 0/ surface-wave is used as the primary source of free space radiation". After reviewing the references, and analyzing the parameters published, it does not appear that the antenna can operate in the manner claimed.
