Re: Coax fed antenna
Hi Mustapha,
Thank you for the reply,i have the HFSS tutorial where vacuum is used as substrate.My problems are how to determine the input impedance of an antenna fed with a coaxial cable? ,and which substarte should i use (Teflon for real coax cable with outer and inner conductors-(copper or PerfE???) or vacuum).
Could you run the project,it want take a lot of time, have a look to the S-parameters,when compared with author's one ,a shift at 8 GHz exists for the zero order mode and high return loss -9 dB for the first negative mode.!!!!
I'm so disappointed with this project because i've tried everything but without results and as you said Mustapha there's a problem with the coax cable.
Thanks.
