本論文之研究目的為設計可涵蓋於無線區域網路之三頻與雙頻圓極化平面天線,並且可應用於無線區域網路 (WLAN, Wireless Local Area Networks)頻段,結構設計採用平面式槽孔及單極天線設計。首先在第二章節裡提出應用於無線區域網路之圓極化菱形槽孔天線,利用菱形槽孔以及不對稱之殘段造成圓形極化波現象;第三章節介紹具有U形寄生元件之應用於無線區域網路雙頻圓極化單極天線設計,使用與共平面波導(CPW)饋入線相連的倒C形金屬線段,以及U型寄生元件達到雙頻圓極化操作;以及應用於無線區域網路之三頻圓極化單極天線設計,利用從接地面延伸出之殘斷,以及F形饋入線設計出涵蓋WLAN 2.4 GHz、5.2 GHz、5.8 GHz三頻圓極化天線。
In this thesis, the dual-band and broadband circularly polarized planar antenna designs are proposed for WLAN (Wireless Local Area Networks) applications. The proposed configurations are based on the planar slot and monopole antenna to produce a circularly polarized (CP) effect. In Chapter 2, a rhombus slot antenna is fed by a microstrip line with two asymmetric tuning stubs located on the rhombus slot to produce CP characteristics. In Chapter 3, we propose the monopole antenna with a U-shaped parasitic element for dual-band CP operation. Designing an inverted C-shaped monopole and the U-shaped parasitic strip produces CP radiation. In Chapter 4, a broadband CP monopole antenna is presented for WLAN applications. This design uses a extended tuning stub from ground plane and a modified F-shaped CPW feed line to reach CP operation and the operating bandwidth can cover the 2.4 /5.2 /5.8 GHz WLAN bands.
