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...

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.

Sub: Need specialist
/ expert advice on Antenna & Circuit Co-Simulation using Agilent
Is it possible to co-simulate in Agilent ADS
HB (Nonlinear Circuit schematic) with Momentum (Antenna design).
Basically I want to vary the Power Levels dynamically for my antenna
monitor the radiation patterns simultaneously.
If not, is there any other tool does this job!!!

Your question implies a belief
that the antenna's radiation patttern varies with power. This is not
normally the case, which is why such simulations are usually done separately
- both because they can be, and because there's a lot less work involved
with splitting a system up and analyzing each piece.

It's the Fields not he radiation pattern...
I should be able to see E & H fields when I cosimulate with circuit
Is it possible???
