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。
Design of Printed Compact Dual-Band Slot Antennas
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.
