摘要

本文通过实验研究了OAM天线阵列中介电载荷对隔离特性的影响。将介电常数为2.6的圆柱介质加载到设计为28 GHz的TX/RX圆形8元OAM天线阵列中，并在消声室中测量了OAM模式隔离特性。结果表明，优化后的介质圆柱体载荷在28 GHz频段的宽频率范围内，隔离特性提高了3.2 dB。

Experimental Investigation on Mode Isolation Enhancement for 28 GHz OAM Circular Antenna Arrays by Dielectric Loading

In this paper, we experimentally study an effect of dielectric loadings in OAM antenna arrays on the isolation characteristics. Cylindrical dielectrics with the permittivity of 2.6 are loaded in TX/RX circular 8-element OAM antenna arrays designed at 28 GHz, and OAM mode isolation characteristics are measured in an anechoic chamber. It is confirmed that the isolation characteristics are enhanced by 3.2 dB in the broad frequency range in the 28 GHz band with the optimized dielectric cylinder loading.
