Hi,

I am attaching here my model of the conformal antenna,

1. how can I see the feed location coordinates here? The measure tool is not giving me proper coordinates as global coordinates are at a distance from the patch center and it's a curvature so I can't get the proper X,Y coordinates of this feed.

2. How to add add two copper patches touching the one end to end to the other end of this half arc shape antenna?

Hi @sswh2,

I created two points that give the co-ordinates of the start and end of the feedline. Please see the attached model file.

Can you share a picture or description of how the two copper patches are supposed to be aligned?

Thanks for your help mam, I can't still be able to see the x,y coordinates of my probe, can you kindly fix the probe location exactly like this full-cylinder shape model(attached) into my current half-arc model?

@Shannon_Mistry kindly check

@sswh2 Looks like I attached the wrong model, please find the model highlighting the two co-ordinates with named points.

@Shannon_Mistry thanks, but I need to know the distance of this feed from the edge of the patch , from your coordinate,

I found the x distance is 3.2 , but another point along y from the edge of the patch I can't figure it out how to measure, my feed point should be (3.2,4.8) mm from the two edges of the patch kindly see this attached full cylinder file , can you make my feeding probe exactly at this location in the current half cylinder model like this full cylinder?
