Do you have too thick lines? Coupling effects in EM simulator of MWOffice are calculated accurately for thin lines. Thickness parameter is only for conductor loss calculation.
Try to use configuration of two identical antennas separated by R in deaf chamber. Then:
abs(s21)^2=G^2×lambda^2×(1-abs(gANT)^2)^2/(4×pi×R)^2
where s21 is measured by network analyser, R is distance, lambda is wavelength, gANT is refl. coeff. of antenna and G is test antenna gain
Try using MWOffice, official web site is www.mwoffice.com

All PCB lines in simulation files, e.g. microstrip lines, bends, etc. can be viewed in layout, you can define packages for semiconductors and ICs too. After you finish layout, you can export it as...
Attached is data rate measurement comparing with and without diversity. Its a Bluetooth system (frequency hopping and FEC included) that communicates via serial port and uses two diversity antennas combined in two ortoghonal beams, each beam in own channel. In indoor application, this action is...
Selection diversity with two antennas works fine for me. I use 2.4GHz frequency band and additional uC that monitors the received signal strength and switches on stronger antenna signal.
