| Summary: | 碩士 === 景文科技大學 === 電腦與通訊研究所 === 97 === The thesis mainly discuss a kind of antenna structure parallel to non-ideal ground plane, take notebook antenna as an examples, A notebook antenna suffer from non-ideal ground plane and being parallel to the LCD monitor on the ground; the radiation efficiency of the antenna decreases obviously. This thesis propose three kinds of antenna structures,3D-PIFA,3D-Tab monopole and the compound structure. The compound structure combines the benefits of 3D-PIFA and 3D-Tab monopole structure to overcome the effects of complex environments in notebook. Consequently, better the antenna efficiency and enough BW for WWAN frequency range (824~2170MHz) can be achieved through compound structure. Design procedures and variation of each parameter relative to antenna performance are explained in detail in this thesis.
