摘要

在基站多频段共享孔径天线中，跨带耦合严重影响高频段天线的性能。在这项工作中，这些影响归因于二次辐射场问题。为解决这一问题，设计了具有电磁透明特性的l波段(0.76 ~ 0.88 GHz)天线。该l波段天线具有m波段(1.9 - 2.7 GHz)和h波段(3.3 - 3.9 GHz)电磁透明特性。此外，还设计了L/M双频阵列和L/H双频阵列来验证电磁透明特性。仿真结果验证了该天线在大规模MIMO基站天线开发中的适用性。

Development of A Multi-Band Shared-Aperture Antenna Array

In multi-band shared-aperture antennas for base station, the cross-band couplings have severe influences on the performance of higher-band antennas. In this work, those influences are attributed to the secondary radiation field problem. For solving this problem, an L-band (0.76 - 0.88 GHz) antenna with electromagnetic-transparent characteristics is designed. This L-band antenna has M-band (1.9 - 2.7 GHz) and H-band (3.3 - 3.9 GHz) electromagnetic-transparent characteristics. Furthermore, an L/M dual-band array and an L/H dual-band array are designed for proving electromagnetic-transparent characteristics. The simulated results validate the applicability of this proposed antenna for massive MIMO base station antenna developments.
