摘要

本篇論文主要對手持式多媒體PDA行動裝置中多頻帶的天線進行設計分析與研究。
本論文將探討兩個天線主題，第一個天線主題為四頻天線設計，其頻帶含蓋範圍從GSM-900(Global System for Mobil Communication,全球行動通訊系統,頻帶:880~960 MHz)、DCS-1800(Digital communication system,數位通訊系統,頻帶:1710~1880 MHz)、PCS-1900(Personal Communication Services,個人通訊服務系統,頻帶:1850~1990 MHz)、WCDMA-2100(Wideband Code　Division Multiple Access,行動通訊與固網整合系統,頻帶:1920~2170 MHz)等四個頻段。
第二個天線結構為結合攝影機可應用於無線區域網路2.4/5.2GHz雙頻操作，新穎和簡單的雙圓環型單極天線設計。主體結構為一個直立的ㄇ形圓環的金屬棒加上一個短金屬線在結構，透過1/4波長的設計概念，調整金屬線的長度，可簡單的製造出雙頻的單極天線，降低了設計複雜度與製造成本，結合了內建式照相機，利用其非金屬的空間放置天線，可節省寶貴的電路佈局空間。

The aim of this paper is to design an antenna for multimedia PDA mobile handset applications.
In this thesis, we will investigate two types of antenna systems. The first system is a design of Quad-band main antenna which can meet the requirement of four wireless standards, namely, GSM900 (Global System for Mobil Communication, Frequency: 880~960 MHz), DCS1800 (Digital communication system, Frequency:1710~1880 MHz), PCS1900 (Personal Communication Services, Frequency:1850~1990 MHz), and WCDMA2100 (Wideband Code　Division Multiple Frequency: 1920~2170 MHz).
The second antenna structure is to combine a monopole antenna with a built-in camera module for WLAN 2.4/5.2GHz applications. A novel and simple dual-band dual-round strip monopole antenna is proposed, where the main structure is a ㄇ- shape metal radiation strip combining with a short L-shape metal radiation strip . The effective total length of the dual-band monopole antenna can be tuned utilizing the quarter wavelength design concept. This simple concept greatly lowered the design complexity and reduced the cost of manufacture. Further, the antenna can be placed on the non-metal spacing of the built-in camera module and thus can save valuable space for circuit routing.
