Hi,all
The planar transmission line has several types.
Such as microstrip line,coupled line,coplanar waveguide,slot line.
These transmission line's signal line and the ground plane are metal constitution (PEC).
I want to know that the transmission line signal line part is a metal(PEC) and...

Hi,all
I use HFSS V10 to simulate circularly polarzation wave incidence to the PEC or PMC.
If use LHCP wave or RHCP wave,polarization angle and polarization ratio hypothesis method?
Thanks.

Hi,all
I want to use HFSS V10 to design 2.4GHz planar dipole antenna,but i did not know how should design.
May give me planar dipole antenna the design model?
Or is some introduces planar dipole antenna paper also to be
allowed.
Thanks.

pmc ground plane
Hi,everyone
I am using HFSS to simulate dipole antenna near PMC ground plane. the dipole is parallel close to the PMC ground plane.
when i simulate this dipole antenna for 2.4Ghz centre frequence and place it very close to PMC ground plane 1mm to be exact i get good matched...
So Gain is the supposition power has complete delivers the
antenna and the survey radiation power and the power input ratio?
But Realized Gain is the survey actual delivers the antenna the power
and the radiation power ratio?
In HFSS V10 if must look at the antenna Gain Can have two options in the result,
respectively is Gain and Realized Gain.
I do not understand these two have any to be different.
May ask the expert to help me to explain.
Thanks.
ground plane dipole directivity
Hi,everyone
I am using HFSS to simulate dipole antenna near metal ground plane. the dipole is parallel to the metal ground plane.
when i simulate this dipole antenna for 2.4Ghz centre frequence and place it very close to ground plane 1mm to be exact i get...
ideal dipole antenna
Hi,everyone
I am using HFSS to simulate dipole antenna near metal ground plane. the dipole is parallel to the metal ground plane.
when i simulate this dipole antenna for 2.4Ghz centre frequence and place it very close to ground plane 1mm to be exact i get badly matched...
Hi,All
After I use HFSS to simulate period of time to be able to have the
following wrong news.
Why don't I understand can make such mistake.
Why may some people tell me to be able to make such mistake?
Thanks.
Hi,evertone
Uses Radiation and PML in HFSS can have four kind of types to provide the choice.
The following figure shows.
May ask each position to help me to illustrate these four kind of
types the significance as well as the use opportunity?
If has the model file to explain that was...
Hi,everyone
I use Master and Slave to simulate the infinity FSS.
If I use the plane wave normal incidence to FSS(Frequency Selective Surfaces),And wants to observe the far field reflection and the penetration
polarization of situation.
Because I want to design one kind of FSS,When a linear...
Hi,everyone
We usually can see on Paper some antenna the design is High gain and high
directivity.
But I do not understand the antenna Gain and directivity have any to
be different.
I knew these two relational type is G(Gain)=radiation efficiency*D(directivity).
But I did not understand to...
grating lobe
Hi,all
Recently was looking at the related antenna array design the
literature material.
Has speaks of if each antenna element each other spacing is larger
than 1/2 wavelength,Can produce grating lobe.
Asked what grating lobe and sidelobe do have is different?
Thanks.
