Hi everyone,
I have troubled about distributed small signal model for fet in ADS tool to simulate multi-fingurered HEMT devices,
Someone help me !
How can I define the small-signal circuit to Y-parameter and Y-parameter per unit width of propagation?
How can I set up the frequency dependence...
Thank pancho_hideboo,
However I want to measure the intrinsic parameters: Cgs, Cgd, Cds, Ri, gm, gd and Tau which are as functions of source-to-gate voltage.
Hi everyone,
I have tried to calculate the intrinsic parameters (Cgs, Cgd, Cds, Ri, gm, gd and Tau) which are functions of the biasing conditions by ADS tool but I cannot simulate it.
How do I measure them in ADS tool?
Hi shahid78
I think the dispersion diagram of periodic structure using unit cell or eigen mode solver in CST only help u to find out the natural physical.
But the problem of EBG is application on the real.
When using EBG in application, for example: the antennas, u will see that EBG is more and...
learning feko
peleda, i think:
1. you used finite ground plane
2. may be neither not union cuboid with metallic or using FEM when feed line contact with cuboid
with feko, you can use infinite ground plane and MoM method so easy to simulation, but not exactly ^^!
to use finite ground...
Feed design
hi horzcat,
you can use hfss to simulation horn antenna, however you can use feko to simulation this. feko is powerful with antenna placement. it's useful for you when designing satellite
if you use hfss, you can use waveport
if you use feko, you can use wireport like its example or...
yeah, mvr
i think that is not nomalized method about simulation microstrip antenna.
when to place the feeding edge inside, apart of substrate ( may be small or very small) was not transmited by electromagnetic field. This is no problem with the width, but it is problem with volume (of substrate)...
example feko
thanks mvr
but it's difficult to make antenna with edge port feed
i used to try doing this method before. but when i compared the result of simulation with hfss software, i recognized that this result is not as exactly so hfss. besides it's not exactly very much: use => not use
i'm...
aerial antenna feko
hi all
i'm a newbie, now, i'm using feko v5.2
but i don't understand many problem about microstrip fed and cpw antenna when using feko
when simulating microstrip fed antenna and cpw antenna, i use edge port to excite metalic_face to others but both of the metalics contact...
