*** What software can simulate "large arrays"?

[m87rahimi]

Hi all
what software can simulate large finite phased array antennas?(1000 element)
has any body some information about finite array design from infinite array results
by convolution technique?
thanks & regard

hi,

refer to this topic array simulation software



you can also refer this topic for antenna design software

Use Wipel-D
Special tool for Array simulation

hi,

free or any trail version Wipel-D available? need license for that?

**broken link removed**

Also for array design look at this tool
**broken link removed**

I suppose you need to ask companay for seperate tool.
They give quick responce.
register & Email them

This paragraph is from “phased array antenna” by R.C.Hansen pp 273 , 274
Does anyone know what is the mining of “aperture” in this paragraph ?

“First, the scan element pattern (SEP) is computed for the corresponding infinite array. This SEP is then Fourier transformed [usually by discrete Fourier transform (DFT)] back to the “aperture”. Third, a periodic structure consisting of equally spaced finite arrays, with each array having the desired amplitude distribution and scan phase, is transformed. Fourth, these two transforms are convolved. Next the result is inverse transformed to get the SEPs over the periodic structure. Last, the SEP for one finite array is extracted, and multiplied by the isolated element pattern, yielding the final finite array scan element pattern.”
Thanks and regards
