    How to plot radiation pattern in Labview

    Hi anybody know how to plot the radiation pattern from spectrum analyzer on Labview. I need to measure the radiation pattern for spiral antenna. I made the lab setup with transmitter and receiver with spectrum analyzer, signal generator and PC. The PC which is connected to spectrum analyzer has...

    Balun to feed spiral antenna

    hi mateusbatera thank you for your reply. I am looking for your paper. as you told in previous mail, substrate height has an effect in impedance. unfortunately, i have the TR 6010 rogers with a height 0.635mm. I think, according to inner and outer radius, i can set the lower and upper...

    Balun to feed spiral antenna

    hi thank you for your reply. as you told, i am also using RT6010 Roger as the substrate in CST. in this case i set the lower frequency as 2GHz and upper frequency as 20GHz. so these spiral parameters don't affect the above frequency or do i have chage the inner and outer radius according to this...

    CST-Microwave studio - need help calculating power

    hi ravi8331 I have to calculate imput impedance of spiral antenna. Do u know how to find S11 in CST for specific reference impedance i mean S11 = Z - Z0/ Z+Z0 from this equation we can find Z (input impedance of spiral antenna), Z0 = 50 ohm (feed line impedance). so i need S11 to calculate Z...

    [SOLVED] CST MWS problem: periodic boundary + waveguide port

    I also had same problem. but i have set the all boundary as open add space. then i didn't get any such problem. but it will increase no of mesh cells.

    Pls help how to set the mesh size & stimulate port in HF

    Re: Pls help how to set the mesh size & stimulate port i Hi Ankesh I have designed two arm archimedean spiral antenna using CST. The results look resonable. But when i increase no of antenna i mean to get arrat antenna, i couldn't simulate. because no of mesh cells increase. But my software is...
