Patent ID: 8903684

Claim:
A non-transitory computer readable medium including a computer program stored thereon for determining an optimal number of feed elements in an antenna for forming multiple beams, the computer program comprising instructions for causing the computer to perform the steps of: computing a target efficiency of the antenna based on information associated with a performance requirement of the antenna; generating data that corresponds to a curve indicating a relationship between an efficiency of the antenna and a number of feed elements, the curve showing a plurality of antenna efficiency values each corresponding to one of a plurality of feed element numbers; wherein the generating comprises: estimating the efficiency of the antenna and the number of feed elements having at least a boundary signal level among a plurality of feed elements based on a deviation angle of the antenna; and generating data for estimating relationship between the number of feed elements and the efficiency of the antenna based on a result of the estimation; outputting the optimal number of feed elements corresponding to the target efficiency of the antenna based on the data that indicates the relationship between the efficiency of the antenna and the number of feed elements.
