    [SOLVED] LPDA design parameters for receiver and transmitter

    Thanks for your answer! So if i connect ground plane to LPDA i can improve my transmitting and receiving characteristics?

    [SOLVED] LPDA design parameters for receiver and transmitter

    I mean one antenna to work as transmitting and receiving antenna. No simultaneously. For simultaneous work exist some kit MIMO. My teacher ask me which construct parameters LPDA must to have to work like transmitting and also receiving antenna and i dont know what he means. :D

    [SOLVED] LPDA design parameters for receiver and transmitter

    Yes. But have to by some construct conditions to work like transmitting or receiving antenna no?

    [SOLVED] LPDA design parameters for receiver and transmitter

    Yes. I know this things but my question is different. How design LPDA to work like transmitting and receiving antenna? First condition is VSWR<1.5 and other conditions?

    [SOLVED] LPDA design parameters for receiver and transmitter

    I know this things. But i dont know which construct parameters have to be satisfy to LPDA work like transmitting and receiving antenna. Or is this necessary? I i have LPDA designed to frequency range 700 MHz - 1500 MHz so this antenna will work like transmitting and receiving antenna because...

    [SOLVED] Optimization LPDA in CST

    Hello. I have planar LPDA in CST. Freq. range 700 MHz - 3GHz. I modeled and simulated this antenna in CST 2016. But result for lower freq. is bad and also Sparameter isn't under -10 dB. So I must optimize this antenna and here is the main problem. I set in Optimizer parameters which a want...

    [SOLVED] Designing Printed Log-periodic dipole array in CST

    Hello. I have this problem. I have thesis Log-periodic antenna. Now a must design this antenna in CST Studio. But i dont have idea how. :cry: I have all calculations for construction of this antenna (Log-periodic). For all calculations i use book Antenna Theory by Balanis. My teacher recommend...
