RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...

trace length to Antenna feed point - RF Cafe Forums

RF Cafe Forums closed its virtual doors in 2012 mainly due to other social media platforms dominating public commenting venues. RF Cafe Forums began sometime around August of 2003 and was quite well-attended for many years. By 2010, Facebook and Twitter were overwhelmingly dominating online personal interaction, and RF Cafe Forums activity dropped off precipitously. If the folks at phpBB would release a version with integrated sign-in from the major social media platforms, I would resurrect the RF Cafe Forums, but until then it is probably not worth the effort. Regardless, there are still lots of great posts in the archive that ware worth looking at.

Below are the old forum threads, including responses to the original posts.

Post subject: trace length to Antenna feed point.
Unread 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?

Thanks

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
2. Radiation from / Susceptibility of trace

Suck it and see
