Abstract

Green´s function and finite element methods were used to investigate the propagation characteristics of a conventional rectangular waveguide with an enclosed septum. Derivatives of this structure will ultimately be used to form laterally closed TEM horn antennas. Conditions were determined which would guarantee single mode TEM operation. A waveguide impedance for this mode of operation, which is frequency independent and possesses the characteristics of the conventional transmission line impedance, was defined and computed for a range of variables. Such devices will find applications in ultra-wideband systems.
