hfss_antenna_cpw
Hi
I am working with a CPW-fed folded slot antenna and I am using waveport in HFSS.
The CPW was designed to has an impedance of 50ohms .The size of the waveport was: width =3(s+2W) and height =7H, because Strip line (S)>substrate thickness (H). Port only simulations showed...
Hi !
I’m trying to simulate a folded slot antenna in HFSS. However, I found that the Z parameters response, strongly depend on the size of the substrate in the X and Y direction. Of course I kept the thickness of the substrate constant and the air box radiation is lambda/4 high. Please, could...
e_eff ?
Thank you so much for your reply.
Ok, I understand the importance of the effective dielectric constant, but what are the relationship between electrical length (cm) as appears in "Network analysis appliyng the 8510TRL calibration for non-coaxial measurements", (pg 16) and physical...
trl line length
I am trying to create a TRL standard, but I am not sure what line lenght is correct to use.
According to "Network analysis appliyng the 8510TRL calibration for non-coaxial measurements", (pg 16) the optimal line length is chosen by
Electrical length(cm)=15/(f1(GHZ)+f2(GHz))...
Hi!
I'm designing a microwave switch and I'm using CPW to connect it to RF Probes. I mean, I added pads to connect the switch which is smaller than pads dimensions to Probe tips (GSG) because I am using a Probe station. The substrates used are GaAs and silicon. I wish to know if the TRL...
Hi!!
I am simulating a CPW (attached picture), using 2 dielectric materials as substrate. I know the rule of thumb for defining wave ports when I use only one dielectric (width wave port =3(2*w+s)) and (length wave port=4h)and it woks!, but when I applied this rule for two dielectrics assuming...
Are there any examples about CPW using HFSS?.
I think port_tutorial_CPW.ppt attached is good. It explains the design of the CPW in HFSS. However I had problems defining integration lines and E Field do not go from strip line to ground side planes.
Please could someone email me some...
Hi!
I'm designing a CPW (HFSS) and I had problems with integration lines. Please I need information about Coplanar waveguides using HFSS.
I will appreciate your help, and please I new and I do not have enough points to download files, so please send it to my personal email: mfcordoba@hotmail.com
