摘要: | 隨著智慧型手機與3G手機的普及化,多頻帶天線設計的需求越來越多。在益趨小型化、薄型化的手機機殼中,多頻天線設計的複雜度將大幅增加。一般來說,手機天線的擺放位置、使用材料、使用面積與體積、手機天線的高度都是內置天線重要的課題。本論文將著重在使用單塊印刷電路板雙層金屬面的內置天線設計,雙層金屬面使用Via Holes來做連接。這類雙層天線設計包含PIFA與Patch天線兩種共振模態。基本的設計技巧、模擬與量測的特性比較都是主要的討論範疇。 Nowadays, wireless communication technologies have become widespread in the world, and the mobile phone performs a leading role in wireless communication. The pursuit of manufacturing smaller and better cell phones increases day by day and combining multi-systems in a single smart phone is the current trend in recent years. Thus, the antenna design for handheld devices turns into a challenge. The location of the antenna, the material used, and the size of the antenna are the main concerns in antenna designs. This thesis concentrates on dual layer antenna design on the Printed Circuit Board for cellular phones with two resonant mechanisms, such as PIFA and patch resonance. Details of the design are presented. Simulated and measured antenna characteristics are also presented and compared with each other. |
