Non-linear optimization of the excitation coefficients of an array antenna of a large-number elements to reduce the amplitude ripples in the mm-wave hotspot area illumination

摘要

A 60GHz compact-range communication system is designed for coverage to 30cm width and 10m distance by an uniformly excited array antenna of a 64×64-element array antenna. The experiments showed that BER decays in non-far region which could come due to the ripple of the field. In this paper, we obtain new excitation coefficients to reduce the ripples thoroughly by using non-linear optimization.
