| Abstract: | In this paper, design of a radial power combiner at microwave frequencies has been presented. This structure combines 16 coaxial inputs together and creates one rectangular waveguide output of type WR-187. Although complexity of the proposed combiner compared to combiners with coaxial output has increased, its return loss and VSWR have been improved. In order to achieve a good matching in its high frequency response, a fast tune technique has been applied to design procedure. In its design, a rectangular waveguide has been used together with its radial structure but symmetry among its ports and its phase and amplitude deviations have remained at standard values. Also, in its design, in order to avoid corona breakdown strength of electric field has been controlled and reduced. |
