online calculator that designs circularly polarized microstrip antennas with a selectable input impedance. The tool calculates the antenna dimensions and probe position that generate both circular polarization and the user-defined input impedance. We invite the antenna design community to visit our web page at:

http://www.lap.ele.ita.br/microwave_tools.html
And check our tool named: CPRMA Calculator, any feedback is greatly appreciated.

At the same web page, there is an additional tool that finds the available universe of input impedances for a given design (dielectric substrate and frequency of operation). This allows the user to determine beforehand if a particular impedance is achievable.

The tool is named: CPRMA Zin Universe

A shareable pdf of the published work is attached to this message.
Keep in mind the web page is still under construction, so we apologize in advance for any technical difficulties.
