WIDEBAND TWIN BEAM ANTENNA ARRAY

摘要

A wideband antenna includes a plurality of radiating elements (51-53) arranged in an array (50) and a feed network (10). The feed network includes at least one frequency dependent power divider (20) for varying the amplitude of a signal provided to at least two of the plurality of radiating elements as a function of a frequency of a signal. The feed network may further comprise a plurality of inputs and the antenna may produce a plurality of beams. The frequency dependent divider may comprise a power divider having a first output and a second output, a 90° hybrid, having a first input coupled to the first output of the power divider, and a second input, and a delay line, coupled between the second output of the power divider and the second input of the 90° hybrid.
