Antenna & Circuit Co-Sim using ADS

Need specilist/expert advice on Antenna & Circuit Co-Simulation using Agilent ADS


Is it possible to co-simulate in Agilent ADS
Between HB (NonlinearCircuit schematic) with Momentum (Antenna design).

Basically I want to vary the Power Levels dynamically for my anttanna input &
monitor the radiation patterns simultaneously.

if not, is there any other tool does this job!!!

Thanx,
manju

Practically all EM programs are linear so your absolute power level is moot, and I don't know of any that allow port excitations using harmonics. However there is no reason why the ports couldn't be fed with a harmonic source. It would be neat to see a current density animation with a square wave source. I thought about doing this by capturing each frame from a grayscale animation and then averaging the frames at each time-step together using Photoshop. Care would have to be taken to align the phases and time length correctly.

You may have to do a similar procedure. Record the tone frequencies and levels from a HB simulation, then run a series of antenna simulations for each tone. You could then take, for instance, the E-plane pattern data (must be complex and non-normalized) for each simulation and average them all together to get the full pattern.

The concept is simple but you would have to do allot of simulations to get a full 3D pattern. You wouldn't want to do it by hand so a good scripting environment is needed. You could pull this off all within in Microwave Office but since the pattern data is normalized don't forget to multiply it by your tone power.

Sounds like an interesting project.

Great that Microwave Office helps to solve such a difficult problem.

Thank you very much, I will try the suggestions....

there is any tutorial for EM cosimulation ?
thx in advance
