摘要

本文提出了一种利用带状线到槽线转换的宽带功率分配器。功率分配器使用两条不同的传输线——带状线和槽线。槽线与带状线成90度角蚀刻在地平面上。采用改进的开/短端结构来实现宽带性能。仿真结果表明,该功率分配器在2 ~ 8ghz频段内回波损耗优于12dB,插入损耗小于1.0dB,隔离损耗优于7dB,相位不平衡约为180°±0.2°,幅值不平衡约为±0.03dB。所提出的装置具有尺寸为30mm×35mm的紧凑尺寸。

A novel compact wide-band out-of-phase power divider based on stripline-slotline transition
In this paper, a wide-band power divider utilized stripline to slotline transition is presented. The power divider uses two different transmission lines- stripline and slotline. The slotline was etched on the ground plane at an angle of 90 degree with the stripline. An improved open/ short end structures were employed to achieve the wide-band performance. The simulated results show that the proposed power divider exhibits a return loss better than 12dB, insertion loss less than 1.0dB, isolation loss better than 7dB, phase imbalance about 180°± 0.2° and amplitude imbalance about ±0.03dB across the band from 2-8GHz. The proposed device has a compact size with a dimension of 30mm×35mm.
