Pull out the antenna, adjust the potentiometer to the maximum, can widen the search.
将天线拉出，调节电位器至最大，可扩大搜索范围。

The antenna selection algorithm is the exhaustive search method. Its computational complexity grows rapidly as the number of antennas increases. It is quite impractical.
穷举搜索天线选择算法的计算复杂度随天线的增多变大，影响实际应用。

Numerical simulations show that the search variables should be selected as less as possible in virtue of apriori information on the antenna under test and near-field measurements.
