Shaped-Pattern Synthesis with Amplitude Sub-Array Configuration
2021 International Conference on Microwave and Millimeter Wave Technology (ICMMT)(2021)
Abstract
The paper proposes a two-layer penalty-based algorithm for shaped-beam synthesis with amplitude sub-array configuration, where each sub-array is controlled by an amplifier (or attenuator) and each radiating element is fed with a phase shifter. Different from the reported methods, the shaped-beam pattern can be obtained by jointly optimizing the sub-array configuration and the corresponding sub-array excitation. Several numerical simulations show the effectiveness of the proposed algorithm when the number of sub-arrays is given.
