Hi all members! I'm a newbie in antenna design. I have a question hope every one help.
I'm designing a rectangular patch antenna. I used formulas in book Antenna Theory: Analysis and Design of Balanis. But when i simulate by using CST transient solver, the resonant frequency is quite different from the theory. Theory is 3.5 GHz and result of simulation is 3.36 GHz. I'm use FR-4 lossy for substrate. So i want to ask everyone why have a difference between theory and simulation in CST???
Thank you very much!
