Abstract
A power distribution network is disclosed for use in a frequency scan antenna element. A microwave signal applied to the input of the network is power divided and phase shifted so as to provide, at a plurality of output ports, signals of equal amplitude and, at a design frequency, phase equality. The signals appearing at the output ports are phase delayed relative to the signals at adjacent outputs such that an input signal frequency other than the design frequency presents a wave front across the output ports angled away from the normal to the output ports. The present invention discloses a series-parallel configuration of the power distribution network which provides improvements over both the pure-series and the pure-parallel configurations of the prior art.
