Hi there,
I am learning RF antenna design. I want to design a circular patch antenna with coaxial feeding method.
I have read a book Antenna Theory: Analysis and Design edited by Balanis. However, I could not find how to define the location of Coax feed point for circular patch. In chapter 14 Balanis only gives a sample for rectangular antenna.
Could anyone help in formulas about calculating the location of coax feed point in circular patch antenna? I am highly appreciated!
