摘要

本文提出了一种基于近场耦合的本振进给方案。研究了两个单馈电元件和微带阵列之间的耦合效率，表明通过适当的设计可以实现良好的功率传输。在进给过程中，进给信号的幅值和相位对制造和装配公差引起的位置偏差不敏感。该方法具有良好的性能和简单的结构，是大型阵列本振馈电方案的理想选择。

A novel scheme of local oscillator feeding based on the near-field coupling

In this paper, a novel feeding scheme of local oscillator feeding based on the near-field coupling is proposed. The coupling effectiveness between two single feeding elements as well as the microstrip arrays is investigated, showing that a good transportation of the power may be realized through appropriate design. In the feeding, both the amplitude and the phase of the feed-in signal are quite insensitive to the positional deviation caused by manufacturing and assembling tolerance. This good performance and its constructional simplicity make this method an attractive candidate for the local oscillator feeding scheme of large arrays.
