| Summary: | 碩士 === 國立高雄師範大學 === 物理學系 === 97 === Designs of planar antenna for PCMCIA cards are presented in this dissertation. Three antenna designs have been proposed. These antennas have advantages of low profile, light weight, easy construction and also can be printed on dielectric substrates integrated with associated circuitry on the same substrates, which not only reduces the manufacturing cost but also decreases the required size of the complete system. In this thesis, three advanced design concepts for further studies are presented. Firstly, the design of CPW-fed slot antenna using chip capacitors-loading for operating at the 5.2 and 5.8 GHz WLAN band is presented. Secondly, the design of triple-band monopole antenna using inverted-L structure for operating in the 2.5, 3.5 and 5.5 GHz WiMAX band is presented. Finally, a novel printed monopole antenna is shown. In this design, the open-ended of a rectangular ring obtained multiband to satisfy the dual-network WLAN/WiMAX services.
