    Anyone know how to simlate antenna and used matching network together with CST

    Add external cct. Meaning that i need to draw the outside the antenna? Can I compare the RL before adding and after add the matching ? How about the port setting is that same?

    How to design a helical structure in CST

    Hello, if using macro, i can't change num of turn. you all know how to change it? or others can share with me the easier way to construct the helical. i try many times still can't create it only can create if i follow the num in example template how they calculate the set edge? that's my...
