Re: How to find the exact location for feeding coaxially a rectangular patch antenna
Hi,
First sorry for the late reply, I haven't been checking this forum as frequent. Please let me know if still need help.
Hi haribhuit,
Thanks for your reply, can you provide more details as exactly how to do this?
No problems in simulating the far fields, but then what?? :)
It's very easy actually. In CST menu tab choose Macros --> Calculate --> Calculate analytical line impedance, a new window will open so now choose "Thin microstrip line". Type in your dimensions and press calculate, keep changing your width "W" until you reach around 50ohm for Zo.
No, dimensions remain the same for different frequencies.
In the lab you will always have the same coaxial cable with the same connector for your measurements, whatever the frequency of operation.
That's to the best of my knowledge :)
And I completely agree that your font size at the...
Hi pkg,
5-7dB means you don't have good matching and need to change your feed location. For waveport size, I think you already got a reply to the message you've sent earlier.
