Abstract

Center feed in single-layer slotted waveguide arrays was proposed to increase the frequency bandwidth depending on the long line effect and to obtain a stable main beam unchanged for frequencies. The feed waveguide in this structure is placed at the middle of the radiating waveguides and is composed of a series of unit dividers called a cross-junction. This paper deals with the practical design of a multiple-way power divider for the center feed. A 16-way power divider is designed at 25.3 GHz as an example.
