microstrip producer

I want to design narrow beamwidth microstrip antenna of 10 to 20 degree beamwidth.
can any one suggest me the design?

Hi, vivek1214:

A single or multiple stacked patches normally have much wider beamwidth than 10 to 20 degrees. I think you do need to use an array to achieve it. Regards.

can you suggest me any design?

Hi, vivek1214:

You will need to design it based upon your specifications. When you have the element done, making an array to meet the beamwidth should be straight-forward. Just use 2 or more elements with some spacing between them to achieve the beamwidth you want. Regards.

on which tool i need to design?

Hi, vivek1214:
