Circular polarization microstrip array on a conical surface

Research output: Contribution to journalConference articlepeer-review


This study utilizes the cavity model to compute the input impedance of the patch. It uses spherical wave functions expansion to compute the internal cavity fields and the external radiated fields. The circular polarization of the microstrip element is obtained by exciting two orthogonal modes with 90 deg. phase difference among them. To obtain an omnidirectional azimuth coverage, three microstrip elements are interconnected and equally spaced along the cone surface. The antenna is built and tested and good agreement between the computed and measured results is obtained.
