Abstract
A new structure to radiate circularly polarized electromagnetic waves based on the slotted waveguide antenna is proposed. A combination of a slotted rectangular waveguide and a cavity is used to created waves with circular polarization with very low axial ratio. In an array of the proposed structure, slot spacing close to λ/2 is achievable. Therefore, a planar array with presented waveguide slot antenna can designed with only one main lobe and a directive pattern with circular polarization.
