臺灣博碩士論文加值系統

本論文分別提出應用在多頻段、寬頻帶以及抑制諧波的威爾金森功率分配器。首先，利用一種蘑菇狀電磁能隙結構對傳播色散圖呈現非線性之影響以及傳統威爾金森功率功率分配器上所擁有的倍頻諧波特性，來達到兩操作頻率設計之雙頻段威爾金森功率分配器。其次，利用一全通耦合線架構實現兩任意操作頻率之雙頻段功率分配器。除此之外，本論文以一種兩段耦合線串接之雙頻段威爾金森功率分配器為架構並結合兩操作頻率，來獲得應用在超寬頻系統的寬頻帶功率分配器。最後，使用耦合線具備的電容效應並聯一段擁有電感性之傳輸線線段而得到一共振腔，來實現微型化抑制諧波威爾金森功率分配器。在此篇論文中所提出多頻段、寬頻帶及抑制諧波之威爾金森功率分配器，
其電路量測及電磁模擬之結果都有良好的一致性。

In this thesis, Wilkinson power dividers are presented for multi-band, wide band, and harmonic suppression applications. Firstly, combining the nonlinear dispersion relation in electromagnetic band gap (EBG) structure and the inherent multiband characteristic of a conventional Wilkinson power divider, a dual-band Wilkinson power divider is proposed. Secondly, a dual-band Wilkinson power divider utilizing all-pass coupled lines section is designed and fabricated. By cascading two coupled lines, a wideband Wilkinson power divider is realized for ultra-wideband applications. Finally, by incorporating a resonator composed of a coupled line and an inductor, a compact Wilkinson power divider is presented for harmonic suppression. Both the simulated and measured data show that the proposed circuits have good matching and isolation characteristics.
