| dc.description.abstract | 摘要
在本論文中，我們將研究一微型化雙頻槽孔天線在2.4 GHz和5 GHz無線網路上的應用。在本篇論文提到，天線設計的特點在於體積微型化的設計，而縮小天線本體的大小，不外乎是改變其形狀；而我們利用天線彎曲（meander）及多條槽孔（multislot）的方式來實現；最後天線本體僅10 x 10 x 0.4 mm^3大小。不僅於此，最後天線可在 PCB板邊實現，方便其它積體電路的整合；同時並提供最高超過0 dBi的輻射增益。量測與模擬有不錯地一致性。
此外，提出了一以微帶線饋入方式的新型微型化雙頻槽孔天線；此天線可有效地抑制倍頻及更縮小其體積。
最後，模擬一系列當其金屬元件靠近天線本體時，反射損耗值的表現，以及訊號線靠近天線本體時，反射損耗值與隔離度的表現，均可發現有不錯的特性呈現。 | zh_TW |

ABSTRACT
In the thesis, we investigate a compact dual-band slot antenna for 2.4 GHz and 5 GHz wireless applications. A technique for compact antenna design is proposed. Reduced-size monopole slot antennas with different slot shapes placed on a small ground plane are studied. We propose the dual-band slot antenna with a compact size of 10 x 10 x 0.4 mm^3.This antenna locates at the corner of the ground plane and can be easily integrated with other circuits as a whole in a PCB. The peak gain of the proposed antenna is more than 0 dBi. The measurement is in good agreement with simulation. Additionally, a novel compact microstrip-fed dual-band slot antenna is proposed to achieve suppression of harmonics and miniaturization of the antenna. | en_US |
