Is this artical (of journal) true? I simulated...

Hy,
I have a question about the article that has attached This follow.
The title of artical is "A NOVEL BROADBAND DESIGN OF A PRINTED RECTANGULAR SLOT ANTENNA FOR WIRELESS APPLICATIONS"
By:WEN-SHAN CHEN
Southern Taiwan University of Technology
Tainan Hsien, Taiwan, RO
I inform you that I have gained this article from site **broken link removed**
It semms that figuer 2's reflexations damageness which its simulated and measured is shown in diagram
is not true, because I got same results of simulation on antenna 1 by two different software HFSS and Ansoft Designer which the first one works on the basis of Finit element Method and the second one works on te basis of Moment Method But it was different with its result in artical.
Why the diagram of these two software is different of diagram in the article?

What is important for Asian academics is not genuine results but getting a paper published. These people don't know about scientific ethics and they publish loads of bullocks.

Can it be the simulation settings which lead to different results?

I have heard of a famous university prof who for years published variations on the same theme and had fatal theoretical flaws in the journal articles. It took decades for him to be kicked out and he never got a teaching post again.

There must be some problems with the simulation settings for the disparity between the simulated and reported results.
The reported results are possible as I myself have simulated and experimented similar structures if not the same.

I simulated in CST

All the EM software depend very much on settings... unfortunately you need experience to know what to change... you change to a different software, your previous experience comes to nought !!

hi

i thinck your simulation may be failed
please post ur simulation disign(with out result) in hfss
then i can help

Hi,
Thanks
this problem is solved. One of the parameters(lenght of strip line feed) must be chnged.
