Thanks all.
It seems like it was the "interpolation" alalysis. I am using HFSS and tried the "Fast" analysis. Now the letrun loss is all below 0 db but then my RL is worse over my frequency band of interest. :(
positive return loss
Hi,
I have modeled a partch antenna (including the feed structure). But the problem is when I plot the Return Loss (dB) over the frequency range there is a section where the return loss is > 0 db and reaches a peak of 6dB.
Thats doesn't make sence to me. It's a passive...
winmm32.lib+vc++
I am not sure if it was a typo to summarize C++ as a disaster. If its not, then I think you better come up with that book as we all need to learn why "C++" is a disaster. This sure will be a great contribution to "programming" domain.
I will in a way agree with you on above...
vhdl code for mux & demultiplexer
Coming from the Software Engineering background (long time and various
lang) I had the same issue. Overcoming the 'sequential code flow'
thinking pattern and learning to think in terms of 'simultaneous
signals' is indeed the biggest hurdle. (Note the use of...
Re: What is TSR in C. How can i make my own fonts is turbo c
Just to make sure that you get proper answer,
Are you trying to change the system font of the system. For example the fonst that we see (or used to see) in DOS/Linux console? The come from a char map in the memory and you need to...
IVT = Interrupt Vector Table
-- This is a table maintained by OS for the what function to call for interrupts. So you can think of it as in one column having the ID of an interrupt and the other column contains the function pointer that should be executed in case of that interrupt happens.

Thanks savedadogs! It helped.
I did check the tutorial before but somehow missed last line.
So for those who might make the same mistake..
The last line in the tutorial tells you how to do it.
Hi All,
How can I calculate/plot the Gain and Efficiency of my antenna?
(1) At single/solution frequency
(2) Over the frequency sweep
Apologize about the reposting but I am clueless on this?
Thanks,

Hi,
I feed to feed a Patch Antenna (Edge Fed with MStrip Line) where the Input impedance at the edge of my antenna varies from rapidly over my band of interest. Note: I have resonance at the centre freq but below and above that its comples Impedance.
Any suggestion on what kind of...
Hi Borich,
It helped a lot. Now I know I am in the right track. Thanks for the doc.
A minor issue though,
I haven't set up my feed as MStrip. Right now its a lumped port right at the edge of my patch and I plan to do optimetrics on moving the feed towards the centre (I can roughly calculate...
