how to design coaxial probe feed for circular microstrip antenna
im designning circular microstrip antenna for my final year project.can u guys help me how 2 design the coaxial feed for it and how to determine the position to place them on my circular patch.im using cst software. plezz...
Hi Kristal
There're so many papers about this topic and some closed form equation for that. If you'll feed the antenna by 50 ohm coaxial probe there is formula for radial distance between patch center and feeding point

Design of Patch Antenna using CST started from 92 page,
Model the Coaxial Feed - from 99 page
Good luck
can you give me the link?
