Résumé

Recently, the study of slot-coupled directional couplers has led to compact and elegant topologies for UWB applications. The most common design consists in two elliptically shaped lines coupled through an elliptically shaped slot in a common ground plane. In this paper, this concept is applied to the design of Ku-Band directional couplers manufactured in stripline technology. It turns out that parallel plate waveguide modes (PPWM) are strongly excited, which impacts the overall working of the structure. In order to mitigate this issue, two solutions have been simulated and their results are compared.

Planar transmission line

Planar transmission lines are transmission lines with conductors, or in some cases dielectric (insulating) strips, that are flat, ribbon-shaped lines. They are used to interconnect components on printed circuits and integrated circuits working at microwave frequencies because the planar type fits in well with the manufacturing methods for these components. Transmission lines are more than simply interconnections.

Stripline

In electronics, stripline is a transverse electromagnetic (TEM) transmission line medium invented by Robert M. Barrett of the Air Force Cambridge Research Centre in the 1950s. Stripline is the earliest form of planar transmission line. A stripline circuit uses a flat strip of metal which is sandwiched between two parallel ground planes. The insulating material of the substrate forms a dielectric. The width of the strip, the thickness of the substrate and the relative permittivity of the substrate determine the characteristic impedance of the strip which is a transmission line.

Waveguide filter

A waveguide filter is an electronic filter constructed with waveguide technology. Waveguides are hollow metal conduits inside which an electromagnetic wave may be transmitted. Filters are devices used to allow signals at some frequencies to pass (the passband), while others are rejected (the stopband). Filters are a basic component of electronic engineering designs and have numerous applications. These include selection of signals and limitation of noise.
