OPTIMIZED RADIATION PATTERNS

摘要

An antenna arrangement comprising at least two antenna arrays, each array comprising a plurality of radiating elements being arranged so as to have at least a plurality of corresponding radiating element positions, wherein for each radiating element there is associated an excitation means comprising a magnitude weight and a delay weight, wherein there is a first set of excitation means associated with a first array providing a first radiation pattern and a second set of excitation means associated with a second array providing a second radiation pattern. At least two respective excitation means associated with a corresponding radiating element position of at least two respective arrays have at least two different magnitude weights, and at least two respective excitation means associated with a corresponding radiating element position of at least two respective arrays have at least two different delay weights.
