A Novel MAMP Antenna Array Configuration for Efficient Beamforming
Multi-Active Multi-Passive (MAMP) antenna arrays with reduced number of active elements are studied, for matching the patterns of all-active uniform linear arrays. Based on previous work on MAMP antenna arrays, we present a novel configuration, namely a circular one. By jointly calculating the PEs’ loads and baseband weights of the proposed MAMP array, we can produce a radiation pattern similar to that of a ULA with accuracy up to 97.5%, while the number of AEs is reduced by 33% and in some cases with suppressed side lobes. Moreover, a reduction in the width of the array by 3 times is achieved. Thus, the complexity, compactness and cost of the antenna array can be reduced without compromising the quality of the resulting beam.
