Input impedance of a patch in HFSS

[Saikatdas1]

Hi,
I am very new to HFSS and not very knowledgeable about Microstrip patch antennas.I want to design a corporate feed microstrip array of 8 elements.I have got the dimensions of the patch but dont know how to find the input impedance of each patch and its connecting transmission line's.Also as I am still struggling with the basics,I want to know if bending a microstrip line at 90degre angles (to connect different lines to give a common feed while maintaining its total length as can be found from the formula)will change its impedance?

Thanks in advance
Saikat

Refer to the site
https://www.daycounter.com/LabBook/Microstrip/Microstrip-Characteristic-Impedance.phtml
it gives the impedance of strip line
and search for strip line impedance you will get the online calculators.
i hope it helps.good luck
