## Optimization of probe feed for pentagon patch antenna in ie3d

Hi..i m working on a pentagon shaped patch antenna for 4-12 GHz frequency range with a design frequency of 7.5 GHz. I m trying to use coaxial probe feed. I found good results at one location on patch but the patch is not resonating at designed frequency. How do i optimize the probe feed to obtain resonance at designed frequency?

## [moved] patch axial ratio optimization

how do i optimize the axial ratio of a coaxial fed patch, i cut two notches on the patch and now i want to optimize the dimensions of notch to get axial ratio below 3dB using the optimization function in ie3d zeland. please advise me on how to use the optimization function in zeland

## Help regarding Optimization in IE3D

Respected all, Hello. I am designing a stacked and slotted antenna using ie3d. the same structure when i simulated with FEM based HFSS, gave me four resonances, the result of ie3d is also giving me four resonant points, but the problem is that the RL at two of the four frequencies is less than (above) -10dB. So i decided to assign the probe fee

## how to optimized coaxially feeded microstrip patch antenna using IE3D

dear all i m facing some problem in optimizing the resonant frequency of a coaxially feeded microstrip antenna using Powel Optimizer in ie3d simulator. anybody can tell me........................ i hv already varified the optimization of the resonant frequency of a microstrip line feeded microstrip antenna using Powel Optimizer in ie3d

## what is powel optimizer and E.M optimization

i want to know what is Powel optimizer and E.M.optimization In ie3d.and how can i use it. i have design a sqaure patch which has two slots. i m getting two frequencies 1st is 2.4298,return loss(-13.86) and 2nd is 3.2 return loss(-8.84).i want to use powel optimizer and E.M. optimizer on how can i use it plz guide me

## optimization of microstrip chamfered bends

But i noticed that by changing the length in ie3d, the graph of s11 vs frequency changes and also the value of optimum chamfering changes. Shouldn't it be independent of length according to the formulae? Yes, it should be independent. Did you shift the port reference planes to the bend?

## read IE3D files by matlab

Hey friends I am working on the optimization algorithms , and I try to use the ie3d to optimize antennas, How I can read and write the sim and geo files of ie3d by matlab? Thanx in advance Regards

## 16 WAY WILKINSON POWER DIVIDER

there is an example also, in ie3d 8x8 array of patches with printed power divider. pl

## PSO on Microstrip Patch antenna , need Helps...

PSO is some kind of global optimization scheme. It should be quite good for some sophisticated optimization. Like Gentic optimizer, it does require large number of iterations. It will need to do many sampling. It is good to use ie3d to drive it because of the efficiency and accuracy. It is documented on the Appendix of the user's manual on (...)

## PSO on Microstrip Patch antenna , need Helps...

Good Day everyone, I'm from Malaysia and currently doing a project on: "optimization of Microstrip Patch Antenna Using Particle Swarm optimization" i have done the literature review on PSO and pratical training, doing exercise on antenna design using ie3d.for ie3d antenna design software i still can handle it, but for (...)

## A question about Optimization in IE3D software,

Hi, rf-en: You may not be able to optimize the height on the polygon based editor MGRID. However, you can do it on ie3dLIBRARY. You can do sophistiicated parameterization and optimization on ie3dLIBRARY. By the way, you should upgrade to ie3d 14. The ie3d 14 has integrated layout editor, visualization and (...)

## Need Matlab program that does simulation with IE3D

Does any people have made a matlab problem which can do optimization and call ie3d to do stimulation??I have great difficulty to do this.Please help!!!It is very important to me.

## Problem with optimization in IE3D evaluation copy

hi, i downloaded ie3d evaluation copy frm and tried to simulate a stacked patch antenna. i can run simulation.but when i define some variable for optimization(say patch length) and give for optimization shows some error..saying...this process type is not optimization. kindly help me sort out this prob. with regards abhi

## How to do optimization in IE3D?

Hi, micro_tech: It really depends upon what are your requirements. 1. You will need to define some dimensions of the structure as optimization variables. For example, for a simple patch, you define the size of the resonating edge as an optimization variable. You can define the feed location as another optimization variable. You have (...)

## how to use FASTEM of ie3d

Yes. FastEM tuning and optimization are discussed in the ie3d's user's manual. It is mainly on the polygon editor or MGRID. In fact, it can be done even easier on ie3dLIBRARY. FastEM involves 3 procedures: 1. Parameterization (different on MGRID and ie3dLIBRARY). 2. FastEM Preparation (same on MGRID and (...)

## reg binomial array antenna in ie3d

Hi, Kbmanick: I think you need to design and optimize your feed network for it. You should try to use the SIMULATE AND FIND EXCITAITON feature of ie3d/MODUA. It allows you to find the output power at each port of your array. It should be useful for array's feed network and power distribution optimization. Regards.

## Optimizing 3D structures in IE3D

I am currently working on simulating a so-called ESPAR antenna in ie3d. The antenna consists of one active element (monopoloe) in the centre of a limited groundplane and 6 parasitic elements (also monopoles) placed in a circle around the active element (in the simulations the parasitic elements are loaded with lumped circuits to adjust the antenna

## I feel puzzled in the optimization in IE3D !

Hi I am simulating a bandpass filter with ie3d9.0. During the optimization with the gap between the coupled resonator cells, ther are much difference between the trend and what I want with the curves of s21 and s11. Total three parameters need to be optimized, which are local parameters. But I wonder How to balance every local parameters in thi

## mixed application of matlab and IE3D

Does any people have made a matlab problem which can do optimization and call ie3d to do stimulation??I have great difficulty to do this.Please help!!!It is very important to me.:cry:

## Help,about IE3D design variable and optimization!

Hi, gw_uestc : Please go to the download area of . There is a Zeland Virtual Training and it will show you a movie on it. It is also discussed in the manual. Basically, on ie3d/MGRID, you are defining the locations of the selected vertices as optim variable. You amy also consider ie3dLIBRARY, it is easier to define the variables

## Question about the Print Antenna

Hi, I beleive that ie3d is a good choice for printed antenna, for construction a printed antenna, after simulation and optimization, you must to export your antenna layout in dxf or dwg format then after any required modification in AutoCAD, you can send it for preparing photoplot and etching on PCB. Regards KMPA

## How to tune/optimize the Probe-feed to Patch Antenna in IE3D

HI, Winglj: (1) I seems to me your procedure is correct. You are supposed to be able to define a probe location as an optimization variable. Yes. You should select all vertices on all layers for it. This procedure is shown in the Zeland Virtual Training in . (2). Please define the Negative Level at the ground (z=0) and Positive leve

## How to optimize variables in EM simulation concurrently using IE3D

Hi, mwagner: There are multiple schemes in ie3d to do so. ie3d's default editor MGRID allowsyou to define the locations of some vertices as optimization variables. From the vertices, you can control the shape of your structure. However, MGRID does not allow you to specify the width and length or those high level geometry parameters because (...)
