✦ Synopsis

This paper presents electrical performance and propagation characteristics of self-shielded uniplanar guided-wave structures including circular, elliptic, diamond, and trapezoidal enclosures. Enhanced spectral domain approach is extended to characterize guided-wave property of these self-shielded lines. Particular attention is focused on fundamental mode propagation constant and characteristic impedance of coupled uniplanar line having a practical shield profile. Influence of various parameters of the structure on cutoff frequency of the slotline mode is investigated. Interesting features of the self-shielded uniplanar structures are discussed for design consideration. Results are verified with some data available and presented in support of the technical discussion.
