BEAM FORMING NETWORKS

HI FRIENDS I AM DOING PROJECT ON BEAMFORMING ANTENNAS .. CAN ANYONE TELL ME HOW TO CHOOSE WEIGHT IN BEAMFORMING NETWORKS AND HOW TO DO PROGRMMING FOR ANTENNA ARRAYS IN MATLAB

It depends on what kind of beamforming networks you are using. Butler matrix? Rotman lens?

Added after 1 minutes:

By the way, there are available MatLab code for antenna array.

You can find them from Balanis' book.

THANK U VERY MUCH FOR YOUR REPLY..
I KNOW ONLY HOW BEAMFORMING NETWORKS WORK.. I TRIED PROGRAM FOR ORDINARY BEAMFORMING NETWORK WHICH HAS 4 ELEMENT AND 4 WEIGHTS(PHASE SHIFTER AND AMPLITUDE SCALER) . I GENERATE THE PSK MODULATED SIGNAL AND I GAVE 4 PHASE SHIFTS INDIVIDAULLAY THEN APPLIED THE 4 AMPLITUDE(SCALING) SEPARATELY.. I DONT KNOW HOW TO GET THE COMBINE THE OUPTUT TO PRODUCE THE RADIATION PATTERN... CAN U TELL ME SOME REFERENCE FOR THAT..

I REFFERED BALLONIS ALSO.. THERE IS NO CODING

Hi,

You can refer to "Antenna theory: analysis and design" III edition, by C.A.Balanis.

This book has CD-Rom in matlab coding.

In chapter 6, there are some codes for array factor synthesis.
