Richmond's reaction integral equation method is used to design a rectangular microstrip patch to produce a circular polarization. A rectangular patch with the aspect ratio a = Wx/Wy, in the range 1.015-1.02 and corner fed by a microstrip line, produces circular polarization. For substrate with thickness d = 0.16 cm, a = 1.017 the nearly square patch gives maximum bandwidth.
