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.
