本論文主要是以平面偶極天線作為設計基礎，提出適合於接收地面廣播數位電視訊號之天線設計，文中提出的三款天線設計分別有其不同的技術原理，目標是克服一般偶極天線頻寬不足的問題。寬頻三片式數位電視接收天線設計中，使用外加匹配金屬片達成寬頻設計；末端饋入之修正型偶極數位電視接收天線設計中，使用同向延伸之長短金屬臂達成設計需求；內建於折疊式手機之數位電視接收天線設計中，使用折疊手機之上下系統接地面作為接收天線，配合內部匹配電路同樣可達成數位電視頻帶操作需求。

In this thesis, the study mainly focuses on the terrestrial DTV signal reception antenna. These antennas are designed based on the use of planar dipole antenna, but with different techniques in order to overcome the narrow-bandwidth problem of conventional dipole antenna. In “Broadband Three-arm Dipole Planar Antenna for DTV Signal Reception,” a metal plate is added for achieving wideband operation. In “End-fed Modified Dipole Antenna for DTV Signal Reception,” two arms of different lengths are extended in the same direction to wideband operation. In “Internal DTV Antenna for Folder-Type Mobile Phone,” two system ground planes are regarded as the two arms of the dipole. With the use of an internal matching circuit, good impedance matching can be obtained for receiving DTV signal over a wide bandwidth.
