## conformal antennas

hello

What is the best method to simulate conformal (on cilinder/sphere/cone) antennas/arrays? MOM,FEM,FDTD?

are there good tutorials/books/e-books available?

is there any matlab/c code freely available?

thanks

## Re: conformal antennas

Very difficult to answer man. The answer may vary according to the specific shape of element antenna as well as curvature. MOM/FEM could be OK if you can model it properly. FDTD is not well accepted for array simulatin.

Codes: ooops they are very expensive man. Some days back i got a code for patch antenna from Erip which have been coded by one of his very sweet friend. Search this forum to get that.

If you are looking for a simulator:

If the array is palnar then use IE3D or Ensemble (I know some people who are OK with Linmic). Now if it is non planar then you are in a very difficult zone. Try to avoid FDTD for higher order array and let me think...

Hmmmmmm.....

Well now its a drawing problem. So reject Ensemble.. IE3D can be used but modelling is difficult (I don't know people who use Linmic for it).

Yah.. if your curvature is vey large..IE3D..HFSSSSS.... Hey I think you are not going to put it in the missile head :(

I 've used CST and HFSS for conformal antennas design... There's not a "best method" for analysis, it depends on the shape of your array.. please tell us something more.

MoM is the best

Who is who?

^_^ I am an Antenna Designer.

Recently, I study FMM and AIM. ^_^

## conformal antennas

I am doing research about non-planar (conformal) antennas and I am looking for a versatile tool allowing me to simulate the greatest diversity of non-planar antennas. Obviously I will need a full 3D solver: CST, HFSS, WIPL-D, Fidelity,....

I know CST (FIT based) and WIPL-D (3D MoM based) both have a very good deal for doctoral research.

What do FMM and AIM stand for?

Regards.

FMM stands for Fast Multipole Multilevel . See Chew's book "Fast and efficient algorithms in computational electromagnetics" Artech House, 2001

AIM stands for Adaptative Integral Method. See Bleszynski's paper "AIM: Adaptative integral method for solving large scale electromagnetic scattering and radiation problems" Radio Science, Vol 31 pp 1199-1206, 1996

Good examples of 2.45Ghz patch antenna array on cylindrical surfaces(FEKO simulation + measurement)

and "Coupled Slot-Fed Microwave Slot Antennas on Cylindrical Substrates".

I think that is bigest problem where to find this substrates and how to make conductor lines than simulation.

## conformal

hello kleinesmurf69

there is a book "Design of Nonplanar Microstrip Antennas and

Transmission Lins" from JHON WILEY & SONS, INC. PUBLICATION

i think it's in MCU Fileman.

i look ther

i think it's not there but I saw it ones in the old Filemanager

Plasma,

I have the book. Any other interesting books/weblinks/tutorials you know of?

Thanks.

Regards.
