    bandwidth calaculation

    Many thanks sir. what about this graph?how can i achieve bandwidth? - - - Updated - - - sb told me that you have to draw -10 db line in order to find the bandwidth but in my graph there is no any -10 db line.

    bandwidth calaculation

    Thank you for your reply. could you explain more about sim?I don't know what it means.I just want to calculate bandwidth.Is there another way to achieve that? - - - Updated - - - May be you mean simulation.actually I'm not sure.the frequency is 10 GHz and the ground plane and substrate...

    bandwidth calaculation

    Hi everyone. I want to calculate bandwidth of a microstrip in unit cell mode with floquet port in cst but when I want to calculate from return loss graph there is no any -10 dB line I mean -10 dB line doesn't have any connection with the graph

    microstrip patch array simulation

    could you explain more about L0? is there any equation to find L0? I designed a 32 elements array.could you determine which lines you mean?

    microstrip patch array simulation

    Thank you zorro. That was really helpful. how can i design a phased array microstrip in order to scan with the frequency? I mean that when you change the frequency the beam changes to another direction.

    microstrip patch array simulation

    Thank you for your reply. I want to have a directed beam in a special direction. in that pattern there are two lobes with 15 db gain but i want an antenna with a main beam and one big lobe. - - - Updated - - - thanks. yeah! you're right. what should i do please?

    microstrip patch array simulation

    Hi everyone. recently I simulated a 32 elements array(8*4) with 10 GHz frequency but its farfield is awful and i dont know what the problem is.could you help me please?. this is part of my thesis.

    designing folded dipole in cst

    Hi everyone.I can design a half wave dipole in cst but i'm not able to design a folded one(I have problem in matching two cylinders,i mean making the curves).please help.it is really necessary.sorry about my English.Thanks:wink:
