 03 Nov 2009 7:00 patch antenna input impedance in CST |
|

hi there
for any operating frequency i could obtain the patch length and width. i can also calculate the width of the 50 ohm feed line .. but for proper matching antenna input impedance need to be known ...
how to determine antenna input impedance in CSt .. i know after simulation one can get impedance at port..... is there any way to get impedance at feeding point of antenna?
if input impednce at feed point is known then i can use a trasformer with proper width and length for matching. there should be a ways to calculate edge impedance in CST if any one knows about it then plesae help me here ...
regards
lkminz

hi
you can find the antenna input imedance after simulation
just click the result in the menu bar, there you will find the S parameters calculations and inside which you will see calculate Z and Y matrices
ater selecting Z and Y matrices you will find the input impedance result in the 1D result folder

hi lkminz,
if you are doing microstrip feeding then you can match the impedance for 50 ohms.
