Abstract
This paper presents an edge slotted waveguide antenna integrated with a printed Yagi-Uda director array. The antenna array is composed of ten inclined slot radiators operated at a center frequency of 2.925 GHz. The proposed printed Yagi-Uda director array is used as a different approach to the sectoral horn or the dielectric slab waveguide to achieve a directive beam in the vertical plane. A low sidelobe level in the horizontal plane is obtained by applying Taylor's distribution. To reduce the sidelobe level of the proposed antenna in the vertical plane, the lengths of the elements of the printed Yagi-Uda director array are linearly tapered. The antenna array is fabricated and measured in an anechoic chamber to verify the proposed approach.
