DTV antennas for mobile applications
The study in this thesis focuses on the DTV antennas for mobile applications. By using the novel techniques in the proposed antenna, the narrow-band problem and the radiation pattern of the conventional DTV antenna can be improved. In the first design, the antenna comprises two radiating arms. By adjusting the open gap between the ends of the two radiating arms, large impedance bandwidth can be obtained for DTV signal reception. In the second design, by integrating a coupling portion into the dipole antenna, the full-wavelength resonant mode can be excited successfully and combined with the half-wavelength mode to form a wide operating band. Finally, in the third design, a U-shaped feeding gap is embedded within the V-shaped antenna to excite the full-wavelength resonant mode. Additionally, the dipole antenna can radiate comparable E£X and E£c components, resulting in no nulls in the total-power radiation patterns in the horizontal and vertical planes.
