摘要
A circularly polarized antenna realized by a power divider fed cavity backed slot antenna is presented in this article. The cavity backed slot antenna is constructed on a single layer substrate by using substrate integrated waveguide (SIW) technique. A T-junction power divider with equal magnitude and 90 degrees phase difference outputs is adopted as the parallel feed to excite the SIW backed cavity. Circularly polarized radiation can be generated when two orthogonal cavity modes are excited simultaneously in the backed cavity.
