Abstract
A class of coupled slotline structures with septum and pedestal/groove considering finite thickness of conductors are analyzed for wideband applications of microwave and millimeter wave integrated circuits. The analysis is based on a novel enhanced spectral-domain approach (SDA). Numerical results are presented for propagation constants and characteristic impedances of the fundamental modes. Effects of different structural parameters on cut-off frequencies of first higher-order even- and odd-modes are discussed in detail. The inherent mechanism of these cutoff frequencies of first higher-order modes indicates that the monomode bandwidth can be extended by appropriately choosing the dimension of pedestal in coupled slotlines (CSLs).<>Keywords
