本文提出了一种平面双极化对数周期二元阵结构。per.四臂梯形天线，用于在1.0 GHz至6.0 GHz的频率范围内进行组合极化和空间分集接收。作为阵列拓扑的操作模式之间的天线功率相关性的低值的结果，所考虑的天线阵列提供了四个充分去相关的分集分支，其可以产生高度的分集增益。通过有限元全波分析得出的天线辐射方向图和功率相关性的结果可以很容易地通过天线远场测量进行验证。由于天线阵列的小尺寸要求和大的工作频率范围，这种天线配置非常适合于集成到多标准通信系统中用于分集操作
This paper presented a two-element array configuration of planar, dual-polarized, log.-per. four-arm trapezoid antennas for combined polarization- and space diversity reception in a frequency range from 1.0 GHz to 6.0 GHz. As a consequence from the low values of antenna power correlation between the operational modes of the array topology, the regarded antenna array provides four sufficiently decorrelated diversity branches that may yield a high degree of diversity gain. Results for antenna radiation patterns and power correlation as derived by FEM full-wave analysis could have been easily verified by antenna far-field measurement. Due to the small size requirements of the antenna array and the large frequency range of operation, antenna configurations of that kind are well suited for the integration into multi-standard communications systems for diversity operations
