適用於可攜式多媒體播放設備之新型數位電視接收天線設計在本論文中提出，本論文共有三項不同結構之天線設計，包括:第二章所提出之一新型寬頻平面單極天線設計、第三章所提出之一新型低姿態平面倒U形單極天線設計以及第四章所提出之一新型內藏式平面倒F形天線設計。此三項不同結構的天線設計均具有良好的匹配頻寬、輻射效率以及輻射場型。最後，在第五章中，以第二章所提出之天線設計為研究範例，以簡化之單層介質使用者手部模型以及產品機殼模型，來模擬使用者手部與產品機殼對天線特性之影響，並實際實作取得量測返回損失結果來做驗證比較。

Three novel wideband antennas suitable for DTV (Digital Television) signal reception in the 470 ~ 806 MHz band for Portable Media Playrer (PMP) applications are presented in this thesis. The antennas include a novel broadband planar monopole antenna in Chpater 2, a novel low-profile planar inverted-U monopole antenna in Chpater 3, and a novel internal planar inverted-F antenna in Chpater 4. These antennas all have wide impedance bandwidths, good radiation efficiencies, and good radiation patterns. In addition, we propose a one-layer simplified hand model for achieving efficient and reliable simulation study for PMP antennas. The studied antenna in Chapter 2 is selected to be the example to study the user’s hand effect on the antenna for PMP application.
