Abstract
Methods and apparatuses are provided for advanced antenna system subarray splitter having advanced upper sidelobe suppression. An antenna system includes a plurality of antenna subarrays. Each of the plurality of antenna subarrays having a subarray input; and at least one subarray splitter in communication with the subarray input. Each of the at least one subarray splitter splits a subarray into a plurality of branches, at least one of the branches including a phase taper function and an amplitude taper function. For each of the plurality of antenna subarrays, the phase taper function and the amplitude taper function includes a plurality of fixed phase values and a plurality of fixed amplitude values, respectively, that are configured to not exceed a predetermined sidelobe suppression target for a plurality of electrical tilt angles across a predetermined angular range for the antenna subarray of the plurality of antenna subarrays.
