diffrent results in hfss feko and cst
Hi,
Hope everybody are good.
Please find attached full question with diagrams.View attachment Question.pdfView attachment Question.pdf
A coax-fed patch antenna with dimensions given in table below, is simulated in HFSS, CST and FEKO
softwares.
It is seen that:
The results of the CST software in the case of
- The phase Z component of the electric field on the line parallel to y axis
and
The results of the FEKO software in the case of
- The magnitude of X component of the electric field on the line parallel to y axis
- The phase of X component of the electric field on the line parallel to y axis
- The phase of Z component of the electric field on the line parallel to y axis
- The phase of Z component of the electric field on the line parallel to x axis
and
The results of the HFSS software in the case of
- The phase of X component of the electric field on the line parallel to y axis
- The phase of Z component of the electric field on the line parallel to y axis
are completely different from the results of the two other softwares (despite partial similarity of the field
behavior in other cases).
The question is why it is such different.
