Abstract :
In this paper, a microstrip to slotline transition using different quarter wavelength stubs is proposed and defined as inhomogeneous. The bandwidth of each stub is separately studied and the microstrip to slotline junction is considered as a band-pass filter controlled by design rules. The optimisation of such a filter is achieved by using new design rules implemented in a new CAD tool. At least, simulations and measurements confirm the theoretical approach of this study.
