How to design a microstrip reflectarray ?

[parris]

Now ,I am doing some exercises about microstrip reflectarray and I meet some problems.

First,which software should I choose from HFSS ,IE3D and CST?

second,when I followed a example from a IEEE paper --"Design and Performance of a Microstrip

Reflectarray Antenna ". by Ronald D. Javor, Xiao-Dong Wu, and Kai Chang, Fellow, ZEEE

(IEEE TRANSACTIONS ON ANTENNAS AND PROPAGATION, VOL. 43, NO. 9, SEPTEMBER 1995) and I

simulated the model with IE3D.I used the plane wave excitation, but I did not get the same

result.the E-plane pattern is still symmetrical at theta =0, I dont know what mistake I have

made.

I am anxious and looking forward to your answers and help.Thanks!

Can you help me ?Why I used the plane wave excitation and didnot get the right result?The pattern of E-plane doesnt have a phase shift and symmetrical at theta =zero.

dr jian,any tutorials or examples of reflectarray under IE3D will be more helpfull for me
thanks

alot of examples of plane wave tutorials specially for phase variation againest frequencies founded in cst2008 new version
thanks cst for ur interest
