how to design pattern reconfigurable microstrip antenna in CST

please help if someone can

whats your problem?

i dnt know how to design switches in cst

u can simulated it but you should put and small metal as a switch

can u give me some links or material for designing switches. or designing pattern reconfigurable antenna

modelling a switch in a full wave EM solver is a completely different challenge in itself. you should just remove parts of your line to simulate an ideal switch. then you can look into different types of more realistic switches. (MEMS, pin diodes, etc..)
