Design of a filtering power divider with microstrip-to-slotline transition structures

A filtering power divider (FPD) with high selectivity is presented. Initially, by elaborately introducing two different types of microstrip-to-slotline transition structures and a pair of dual-mode stub-loaded resonators, dual-mode bandpass response is attained in this design. Afterwards, the resistor R is utilised to achieve high in-band isolation between two output ports of the FPD. Moreover, fo...
