That was EXACTLY what I needed. It's even better then I hoped because I don't need iteration variables or loop structures to code. Thanks!

PostForum: Questions Related to Antenna Theory   Posted: Mon May 16, 2016 4:13 pm   Subject: running multiple FEKO simulations in a row
So I have been trying to figure out how to have FEKO run the same test and store the radiation pattern for several iterations. As of right now I'm using an 'i' variable, running the test, saving the ...

It depends on where you want to work in the antenna industry. I currently design and build antennas with only my undergraduate degree in electrical engineering. However one of the jobs I applied for ...

I have been working on this 2x2 MIMO for LTE bands and isolation has been a continuous problem. I've been trying double slit's between the two antennas to help but without software I'm basically just ...

It's just a standard OSL cal using the physical calibration kit.

What you're saying makes sense. I'm basically tricking myself into thinking it's "better" just because it looks smoother. ...

I know the answer to some of my questions will depend on the analyzer but I'm more interested in knowing if anybody has done this. So I was using the average feature (takes the last 16 measurements a ...

PostForum: Questions Related to Antenna Theory   Posted: Mon Feb 15, 2016 6:40 pm   Subject: SWR and Peak Gain
We have an anechoic chamber to test antennas in. I've run several of our regular antennas and the gain numbers come out just fine. Sounds like it's an efficiency issue.

So any tips on improving e ...

PostForum: Questions Related to Antenna Theory   Posted: Fri Feb 12, 2016 6:47 pm   Subject: SWR and Peak Gain
I know that SWR doesn't directly correlate with gain but what would cause peak gain at a high SWR and a low gain at low SWR?

For example, the antenna I am tuning in has an SWR < 2:1 from 1.9 GHz ...

When you say save are you talking about from the analyzer to an output file? The 8753D uses a floppy drive so that may not be possible. I was basically printing off the screen captures and then runn ...

I don't expect it to be the same. I would expect it to be lower at higher frequencies. The wavelength of 698 mhz is larger then 2700 mhz. Say I'm getting a ECC of 0.472 at 698 mhz, then the ECC at ...

Hello, I am currently working on a product that is essentially 2x2 MIMO in the cell bands (698mhz to 960mhz, and 1700mhz to 2700mhz). We are trying to figure out the best spacing and I have been task ...
