Quaterwave microstrip miter design help

[Hi-Tone]

Hi Guys,

I am having trouble making a quaterwave transmission line on a microstrip when I use my MBEND in ADS. When I test on a straight transmission line I get of cause the correct result. If I try to put in some MBENDS in my schematic I hit the center frequency (3 GHz) smoothly IF the length on all three transmission lines are the same.
Now what I really want to is make two of the transmission lines the same length and one shorter so all three of them combined give me the correct length of one quaterwave transmission line without any miter bends. (Please see my attached documents for an overview).
