    Discrete Port or Waveguide Port for SIW antenna in CST

    Hi Everyone, I have a simple question. What port type should I use for SIW Antenna. Discrete port or Waveguide port.? Is it necessary to use only waveguide port excitation for SIW antenna geometries. ? I am interested both in S parameters and far field plot of the antenna.

    Loop Antenna design on FR4

    Ok, I face the problem of resonance, I get a good S11 (-30db) at 900MHz, but with a very wide B.W (500MHz to 2000MHz). I want it to be a narrow band only for 825MHz to 915MHz. What should I do.?
