Abstract EN
So far, a wideband spatial beamformer has been proposed.
This kind of beamformer has a major contribution as its weighting coefficients are real valued in which they can be simply realized by attenuators or amplifiers.
However, so far, the range of attenuation or amplification is relatively large which is not practical for hardware realization.
Therefore, this paper proposes a concept to reduce the range of weighting coefficients hence, the hardware realization becomes practical.
In this paper, a full prototype of wideband spatial beamformer is constructed to reflect the true beamforming performance of the proposed refinement method.
Its radiation patterns obtained from simulation and measurement are compared.
As a result, we can reduce the attenuation or amplification range while some radiation characteristic is remained.
