本論文提出適用於小型化整合型被動元件的天線研究。利用高介電常數的壓電基底材料以及碎形結構來達成體積縮小化的目的。論文一部分將重點放在整合型元件周圍環境對天線的影響，包含封裝外部接腳、內部近距離元件及金屬連接線的影響，結果可提供在設計整合型天線的參考準則。論文另一部分重點放在整合型天線本身的設計，包含高介電常數基底以及不同碎形結構的特性分析；指出小型化天線與輻射效率之間的取捨關係，並且提出改良式接地面的天線設計，藉用實際應用的系統接地面之輔助，明顯改善天線的輻射效率，實現小型化整合型天線的概念。

In this thesis, the study focuses on the antenna design for integrated passive devices. By using the substrate of piezoelectric material with high permittivity and introducing the fractal structures, the size reduction is obtained. Part of the research analyzes the influences of the surrounding environment on the antenna performances, including the effects of external formations, internal components, and interconnections. The results can provide the design rules for developing IPD antennas. The other part of the research emphasizes the design of IPD antenna itself, involving the investigations on the characteristics of substrate and fractals. The trade-off between compactness and radiation efficiency is pointed out, and then a design of modified ground plane is presented. When the modified design is placed on the system ground plane that exists in real system, the radiation efficiency can be improved significantly. Therefore, the concept of the compact IPD antenna is achieved.
