beam forming antennas design using ads

Hi all

1- i want to design butler matrix with microstrip antenna array using ADS2011
can any body advise me how to make it by ADS
i want connect different shapes of antenna with butler matrix and see the behavior of S11
and gain
i want design 4x4 and 8x8

2- how i can plot gain VS frequency using ADS

3- it is possible to make optimization for butler matrix by ADS.


thanks all

Hi, i am familiar with AWR Microwave office and ADS is quite similar to it.
1: Planar structures are simple to design in 2D software, hence butler matrix could be done easily, however achieving proper phase shifts is most critical part. Once you get required phase shift you can try for different antenna shapes.
2: ADS momentum could be solution for plotting Gain Vs. Frequency.
3: Use tune tool in ADS for optimization.

I hear that u can calculate relevant amplitudes and Phases of beam forming via soft called ENSEMBLE...Any ideas on how to use it?
