Dual band GSM/DCS patch

Hey all,
I'm trying for some time now to design a patch that will have
resonance at the GSM band (900MHz) as well as the DCS band (1800MHz).
I used a slotted bent lines, a shorting pin, a parasitic patch, aperture coupled
and just couldn't do it.
The problem is that a good VSWR is not enough, I also need that the pattern
in both bands will have one lobe, and all I get is a main lobe in on band and in the other one two lobes with a Null at the broadside.
Does anyone have an idea how to help me?
