Hi all,
For a 350 µm GaAs substrate with dielectric constant κ= 12.9 and with patch patch length and width almost equal at 5.7 mm , what can be said about the input imedance. CST-MWS simulations are giving me a value of about 1100 Ohms. Can this be expected ? Is there any independent verification ? Normally the impedance is expected to be between 100 and 350 Ohms. Is there any formula that relates the relation between input impedance of a patch antenna with the substrate permittivity ? Thanks for your time.
