| Summary: | 碩士 === 國立中山大學 === 電機工程學系研究所 === 94 === In this thesis, the study mainly focuses on the current trends in development of compact multi-media mobile phone and provides a wideband monopole antenna design suitable for application in wireless communicating system in the near future. By utilizing the planar monopole antenna structure, the proposed antenna design is easy to be embedded into the mobile phone. Further, by using a shielding metal cover, we create a zone with low surface current distribution. This effect will reduce the electromagnetic coupling between the antenna and the electronic elements and make it possible to integrate more related elements into the mobile phones. Finally, we use the simulation software to analyze the dielectric effect caused by the casing of mobile phone and human body on the proposed antenna.
