碩士 === 正修科技大學 === 電子工程研究所 === 94 === Novel designs of modified antennas for DTV (Digital TV) system application are proposed in this thesis. First, planar sleeve antennas with a pair of strips for wideband operations are investigated. In this study, it’s found that a modified dipole antenna can effectively improve antenna bandwidth for achieving DTV system application. Second, compact meandered dipole antennas with coupling stubs are also investigated. By adjusting length and width of coupling stubs, a meandered dipole antenna visibly improve antenna bandwidth and achieve DTV system requirement. Finally, we propose modified monopole antennas with matching network for DTV operation (470MHz~862MHz).
