A new single‐layer feeding mechanism for planar slot arrays is proposed. It makes use of a series of T‐junctions to divide the input power in alternating phase and in arbitrary ratios to the radiating branches. The design procedure presented in this paper also allows for varying input admittances for the different branch lines. A simple equivalent network approach for the off‐center frequency analysis of the feed is proposed. Measured results for a prototype power divider confirm the theory. © 2000 John Wiley & Sons, Inc.
