can you please tell me how to design a sma connector in cst with 50 ohm impedence matching and the specifications to be followed for inserting wave guide port.
 

s parameters for sma connectors

Hi,
can you tell me, what is your aplication ? Becauseit is usualy only metaltube, in the center is teflon and central wire. In attachment very quickly drawn picture.
 
*cst-12 connector*

hi there

well there is built in calculator within CST which you can use to find the dimensions of coax port for the desired input impedance.

then you need to select the substrate face and assign waveguide port to it

i hope it helps

cst connector

thanx for your help.................

but can you help me to calculate the required input impedence for u-slot patch antenna ??

can i use cst for that????????????
 

sma connector cst

hi

well yes you can use cst to calculate the input impedance of your u slot patch antenna.

after simulation just go to the results in the menu bar . there you will find S- parameter calculations and inside its menu you will find calculate Z and Y matrices

which are your required quantities

i hope this helps

structure of sma connector

it really worked thanks for your help............

i have achieved better return loss......
 

assigning port in cst

Hi,

you can try matching in the attachment for example But the proportions you must find experimentaly.... . Power strip have 50 Ohm (CST: Macros - Calculate - Calculate analytical Line Impedance - Thick Microstrip) and on the end is your SMA.
Try find about it for example in books.google.com......

I hope, that I helped you


For example, it is about this picture

Ouu, sorry, you have U-SLOT patch antenna.... so maybe there is only inspiration
 
cst+sma connector

Just one question, why do you want to make SMA connector in CST when you can assign port of impedance 50 ohm?
Do you want to SMA connector as a product ?

Because this topic have name "sma connector in cst" . But yes, of course you do not must make it..... only if the structure requires it.

If you really want to make it,
Search in google for dimension of SMA conenctor & try to implement it.
I think there was one post on this forum 1 or 2 year back, the person has uploaded the file for SMA connector.
I think that it was designed in Vector field concerto..
