1. ## Antenna Placement on Aircraft

Wow. Thanks for your respond @Torben Voigt. It really help
2. ## How to read VSWR, coupling and reflection coef from .out file

Hello everyone, I'm trying to read result from .out file and then i want to make graph with microsoft excel. I can read and make graph of far field but not with VSWR, coupling and reflection coef. Can anyone give a clue? Thanks in advance
3. ## Antenna Placement on Aircraft

oh you are right. thanks again @JIF Now I face this problem. On the polar diagram, maximum total gain is around 4, but when i see the 3d view, maximum total gain is 4.5. Am I doing something wrong again @JIF ?
4. ## Antenna Placement on Aircraft

Oh i get it. Thanks @JIF Can you help me explain why polar chart for phi configuration give me constant value for all degree? My theta (wrapped) configuration give me similar shape if I compare to 3D plot and I think it is correct but the phi configuration not. Here is my result : ﻿

Hello @JIF I come back hehehe. Thank you and also goodluck with your job. I want to ask something again. Is it possible for gain of mounted antenna bigger than gain of free-space antenna? Because it seems that my result show that gain of mounted antenna is bigger than free-space antenna.
7. ## Antenna Placement on Aircraft

:):):):) well @JIF I mean both S1,1 and S2,2 show a constant value. is it normal or not? Because back then if Im not mistaken, one of my friend said that S1,1 should show a curve, not a straight line. and you also said that the antenna is not well matched. how can you know it?
8. ## Antenna Placement on Aircraft

oh okay @JIF I want to ask something again with my result. I ran another antenna placement model ( I put VOR antenna on the vertical tail) and I got the result but I dont know whether this result is corrent or not Here my antenna and my result
9. ## Antenna Placement on Aircraft

hey @JIF why cant I use mesh_fine in local mesh size setting? I got error 16449 :variable not found at position 0 for expression : local mesh size : mesh_fine
10. ## Antenna Placement on Aircraft

alright @JIF Thanks
11. ## Antenna Placement on Aircraft

@mel just 2 more question , what the difference between project and align? and so your step is split the aircraft then make an elips and then project the elips?
12. ## Antenna Placement on Aircraft

Wew thank you so much @mel I really appreciate it . but @mel I want to ask, so you use split tools to create small area next to the antenna? I never use this tools before also the project tools.
13. ## S-Parameters

Thanks @JIF . I really appreciate it
14. ## S-Parameters

Yeah yeah I've got pretty same result here @JIF when i used MLFMM. You know, you make my day. Now I kinda understand how this work, I used wrong method (for this case). But still, I cannot run my aircraft model with MLFMM. Maybe the problem is my laptop
15. ## Antenna Placement on Aircraft

Yeah I think it is corrupt. Here is the file below antenna_dme_versi_15_unioned-2.cfx
