hi everybody.
I'm designing a wideband (6-18GHz) double ridged horn antenna.
the waveguide that i want to use is WRD650. and it can operate in 6-18GHz.
I used HFSS to design the waveguide , and the S11 was very bad(about -4dB). it means that no wave propagate inside the waveguide. i used PML at the end of waveguide but no changes seen.
my question is "how could excite the waveguide at the beginning and terminate it at the end for proper propagation."
the designed waveguide file with HFSS is attached.
WG.rar
thank you
