Hi , i amtrying to design a mivrostrip antenna sensor that can atract tempretur on left side .
The frequency is 868 Mghz , the material is FR4 of 4,4 and 1 mm height .
I have to designe it pn FreeCAD , than export it to open ems .
I started whith the Idea of a patch antenna , but it was very big ,it had 105,17mm width and 82,3mm length .
So i thought of a microstrip meandered dipol antenna . But i didnt found any formula for geometrie calculations . And i don't find enaugh resource for FreeCAD simulation .
Do any one have idea about formula for calculation for meandered dipol microstrip antenna.
Thank you so much
