At present, the DR antennas have on

At present, the DR antennas have only been an object
of investigation in academic laboratories, so that their
field application is yet to be demonstrated. Numerical
simulations and experimental results show that they can
produce favorable radiation patterns and are compatible
with either coaxial or microstrip feed lines. In
comparison with microstrip radiating elements, DR
radiators have better radiation efficiency and operate
over wider bandwidths. Therefore, they should be
considered as one of the candidates for building future
adaptive antenna arrays.

目前，博士天线只已对象调查中学术实验室，以便他们现场应用尚待证实。数值仿真和实验结果表明，他们可以产生良好辐射模式和兼容与任一同轴或微带馈线。在与微带天线辐射单元，博士的比较散热器具有更好的辐射效率和运作在更广泛的带宽。因此，他们应该是认为作为一名候选人为建设未来自适应天线阵列。
