Abstract
En 中文
In this paper, a least perturbation-based method of pattern restoration is proposed. Faulty array elements, have an adverse effect on the radiation pattern of a linear antenna array. Consequently, it is imperative to mitigate adverse effects on radiation pattern. Unlike previous fully compensating approaches, the proposed method optimises the excitation amplitude and phase of only the edge elements. As a result, unlike the completely compensating approaches, the entire array elements do not need to be reconfigured for pattern restoration, reducing hardware complexity. In order to illustrate the effectiveness of the proposed method, 20 elements and 31 elements uniform linear antenna array with random faults have been considered. Further comparative study indicates the acceptability of the method.
