The paper describes an ultra wideband (UWB) planar 180° hybrid in microstrip-slot technology. The device uses three in-phase and one out-of-phase Wilkinson power dividers. The out-of-phase divider uses an in-phase divider with two ±90° phase shifters in the form of double microstrip to slotline transitions in its output ports. The hybrid suffers about 4dB signal loss because of the Wilkinson combiners...
The design of a planar out-of-phase (180°) power divider in microstrip-slot technology exhibiting an ultra wideband (UWB) operation is presented. The device uses a single dielectric substrate and is formed by a two-way in-phase Wilkinson divider with two ±90° phase shifters in its output arms. The phase shifters are formed by double microstrip to slotline transitions that offer compatibility with...
The paper describes the design of an ultra wideband (UWB) microstrip phase shifter employing open and short-circuited parallel stubs loading a main transmission line. To make the device fully planar, the design uses a virtual short and ground slots terminating the stubs. The proposed design strategy is demonstrated in examples of 45° and 22.5° phase shifters. The designed phase shifters exhibit an...
