In this paper, a dual‐polarized antenna that can be used in the 1.7‐2.17 GHz band is proposed. The proposed antenna is a dual‐polarized antenna with parasitic element; it has improved isolation property. The isolation of antenna arrays appears as a synthesis of the isolation of single element and the isolation of adjacent element. The isolation of the antenna array was improved by placing a parasitic element in front of the element so that the isolation signal of a single element and the isolation signal of the adjacent element would cancel each other out. The proposed antenna has a return loss of −15.4 dB or less and an isolation of 31.25 dB or more in the service band, and a gain of 10.87 dBi or higher in the measurement frequency. The proposed antenna is expected to be usable as a dual‐polarized antenna.

利用相位差改善双极化天线阵列的隔离

本文提出了一种可在1.7-2.17 GHz频带中使用的双极化天线。建议的天线是带有寄生元件的双极化天线。它具有改善的隔离性能。天线阵列的隔离表现为单个元素隔离和相邻元素隔离的综合。通过将寄生元件放置在该元件的前面来改善天线阵列的隔离度，从而使单个元件的隔离信号和相邻元件的隔离信号相互抵消。所提出的天线的回波损耗为-15.4 dB或更小，并且在服务频段内的隔离度为31.25 dB或更高，在测量频率上的增益为10.87 dBi或更高。拟议中的天线有望用作双极化天线。
