I know the concept of using weights but in CST I don't know how it is done?
Get up and running as a ham radio operator―or just listen in on the shortwave bands!
Ham and Shortwave Radio for the Electronics Hobbyist shows you, step by step, how to set up and operate your own ham radio station. It’s also perfect for those interested in shortwave listening, without getting a ham radio license. This practical guide covers communications modes, assigned frequency ranges in the United States, details on fixed, mobile, and portable ham stations, antennas, and much more. Ham radio will work even when the Internet and other utilities fail. So get on the air and keep the lines of communication open in any situation!
Inside, you’ll find out all about:
Radio waves and how they travel
Shortwave and allwave listening
Communications modes for ham radio operators, including using the Internet as a supplement
Ham radio licenses and assigned frequency ranges (bands) used in the United States
Wave-propagation characteristics and tips on the bands best suited for use at different times of the day, year, and sunspot cycle
Selecting and installing equipment for fixed ham radio stations
Setting up mobile and portable ham radio stations
Antennas and transmission lines for various frequencies and station types
How to operate your station using popular voice and digital modes
Schematic symbols and Q signals for ham radio operators

If you mean that you have multiport antenna and what to feed it with different weight for each port you can do it in Time Domain Slover
Simulation Stetting->Source Type-> Selection
For CST 2016
That button with name Excitation list will appear
Here you can put different excitation for different ports.
Also in the same window you need to choose excitation type ->simultaneous
For CST 2015
Window where you can put different excitation for different port will appear.
You need to check simultaneous excitation
