Because of the high maintenance needed to monitor and filter spammers from the RF Cafe Forums, I decided that it would
be best to just archive the pages to make all the good information posted in the past available for review. It is unfortunate
that the scumbags of the world ruin an otherwise useful venue for people wanting to exchanged useful ideas and views.
It seems that the more formal social media like Facebook pretty much dominate this kind of venue anymore anyway, so if
you would like to post something on RF Cafe's
page, please do.
Below are all of the forum threads, including all
the responses to the original posts.
Post subject: trace length to Antenna feed point.
postPosted: Tue Jan 18, 2005 9:42 am
Is the trace length between
50ohm balun and a 50 ohm ceramic patch antenna @2.4GHz critical? The
design is CPW Ground with Width = Gap=0.2mm.
Providing I maintain
the 50ohm trace in between, does the actual trace lengths matters? Should
I avoid 0.25Wavelengths?

If the whole thing were lossless and perfectly matched then it doesnt
matter. We know this is not going to be true and you have two problems:-
1. Losses on the trace which will increase with length
from / Susceptibility of trace
Suck it and see
