You should extend the maximum number of pulse.
Solve >> Transient Solver >> Specials >> Steady State (the default of maximum number of pulse is 20) please change this number larger than 20. 50 maybe is sufficient.
I think it's quite easy to simulate conformal antenna using CST. CST has bending feature, that is to bend patch antenna that you want on a cylindrical structure. You can read it in the manual guide.
Hi Aneirin,
For your case, maybe you can try CST MICROSTRIPES. It's include in CST Studio Suite 2010. It has a pretty method solver that is Transmission Line Matrix (TLM) and very suitable for EMC/EMI analysis. You can read the brochure from www.cst.com.
I think electrical length is important in impedance matching especially that using quarter wave. The question is, how to know the electrical length of microstrip line using RF simulator such as CST or HFFS?
Re: HFSS and Windows 7
I've installed HFSS 11 in win 7 x64 successfully. The important thing is change the compatibility of the installer. HFSS 12 can be installed in win 7 x86 without problem.
spiral antenna
In my country, I can make a negative film for etching with a corel draw format. I don't know the process but that is what I do to make a negative film. I'm not doing that by myself, but I send the corel draw format file to the place (third party) that can make a negative film...
cst template antenna spiral design
To design a spiral antenna using microstrip, I prefer using CST Microstripes. This simulator has a feature that is "law". This tool is used to specify the parametric definition of a curve using mathematical functions, so that we can draw a spiral easily. You...
Re: faster simulator?
Yes, I agree with you. CST Microstripes is more user friendly than xfdtd. Using CST Microstripes we can build a complicated model easily, but fortunately the manual is lack I think. Do you have the tutorial or training regarding CST Microstripes?
cst microstripes
To all of you that have experience with CST Microstripes.
Before we run the simulation, we should input the no. of time step at model parameters. The question is, what is the appropriate no. of time step to simulate an antenna? The default no. is 32xlargest dimension. If the...
Hi FvM,
Thank you for your answer. Could you give me the example of balun that using magnetic core? If the balun using magnetic core, is it can fulfill the bandwidth requirement?
wideband balun
Hi all,
I've simulated a equiangular spiral antenna. The antenna bandwidth is 50 MHz - 5 GHz, and the impedance is around 200 ohm. As you know, this antenna is include in a balance antenna category. I want to feed this antenna using unbalance cable. The problem is, how to make a...
